Operation table for palm surgery
专利摘要:
A hand surgery operating table is connectable to a conventional main operating table and consists of a forearm support 8 that is rotatable in a horizontal plane as well as pivotable about a horizontal axis; a base plate 9 carrying a hand support 10; and a number, e.g. seven, of flexible and tensionable arms 11 secured at one end to the base plate 9 and carrying finger-fixing thimbles 18 at the other end. The tension of the arms 11 can be adjusted so that they can maintain their position and can be readily displaced therefrom without having to manipulate their tensioning mechanism 12. The arms 11 may be provided with means for holding instruments. <IMAGE> 公开号:SU1058485A3 申请号:SU813336248 申请日:1981-09-11 公开日:1983-11-30 发明作者:Тари Габор;Хари Ласло 申请人:Метрипонд Мерлегдьяр (Инопредприятие); IPC主号:
专利说明:
The invention relates to a medical technique, in particular to operating tables for hands. The operating table for the hands is known, which contains a support for placing the hand in the form of a pad f. However, this table does not fix the patient’s hand and hand. Also known is the operating table for the hands, which includes a removable console with fasteners, a removable support for the forearm with straps, and armrests 2J. The disadvantage of this table is that it does not provide reliable and adjustable fixation of the fingers to the patient's hand, as well as the convenience of the operation. The purpose of the invention is to improve the convenience of operations by providing reliable and adjustable fixation of the patient’s fingers and hands. The goal is achieved by the fact that in the operating table for the hands, which includes a removable console with fasteners, removable support for the arm with straps and armrests, the support for the forearm is swivel and equipped with a swivel base with a support for the hand and flexible brackets with elastic finger packs with tool holes, with the arm for the forearm connected to the console by transferring a screw-nut closed by a cup. The bending brackets are made in the form of an eyelet, a sleeve, a set of alternating balls and sleeves and a rod connected to each other by a tension wire passed through the holes of each element of the bracket, and the eyelet is installed in a tension device consisting of a support with a groove and a hole the eccentric roller and the lever, and the rod is installed in the cap for the finger, while the length of the sleeve lies within 1.0 - 1.4 of the ball diameter, the diameter of the hole in the balls and sleeves within 1.2 - 1.4 of the wire diameter the length of the ball hole - in Within 0.15-0.2 of the ball diameter, at each end of the guillotine and shrik, internal conical chamfers are made with an angle lying within 50-70 °. Figure 1 shows a table, side view; 2 is the same, top view; FIG. 3 is a flexible arm and tensioner. The table contains a removable console 1 and standard clips 2 with fasteners 3 and 4. The console is made with a sleeve 5, in which the screw-nut gear is installed with a flywheel, frame, b and glass 7, which isolates the bcnt-nut drive screw. At the upper end of the lead screw, the support 8 for the forearm with belts is rotatably mounted, comprising a pivoting base 9 with a support 10 for the hand and flexible brackets 11 fixed to the base 9 by means of a tensioning device 12. In addition, at the upper end of the running gear the screw has an additional arm support 13 fixed by the screw 14, instead of which other elements, such as a tool table, can be installed. The support for the forearm is rotated about the axis 15 by means of the handle 16. The support 10 for the hand has a hinged connection with the support 8 and can be installed in any position with the help of a screw 17. Flexible brackets 11 consist of; of elastic cap 18 for the fingertips, alternating balls 19 and sleeves: 20, strung on a wire 21, on | At one end of which is installed pin 22, and on the other - a finger with a pro-; 23. The attachment i 12 comprises a support 24 with a groove 25 and an eccentric roller 26 with a lever 27. The bracket 11 is connected with the support 24 by means of an eyelet 23, the finger of which is mounted in the opening 28 of the splined hub 29, and the latter is screwed into the hole 30 of the support 24. The bracket is tensioned through the eyelet 23 by means of an eccentric roller 26 installed in the hole 31 of the support and the hole 32 of the eyelets. The cap for the fingers has holes 33 serving to install the rod 22 and to fasten various tools (hooks, tongs, etc.). To ensure the correct position of the wire 21 in any position of the bracket, the sleeve length is chosen between 1.0 and 1.4 diameters. the ball, the diameter of the holes in the balls and sleeves is within 1.2 - 1.4 wire diameters, the length of the ball hole 11; and - Within 0.15 - 0.2 ball diameters, and at the ends of the balls and sleeves, internal conical chamfers are made angle lying in the range of 50 - 70 °. On the table work as follows. The patient's arm is fastened on the arm for the forearm with the help of straps, and the fingers of the hand with the aid of flexible brackets are mounted on the arm for the hand in the desired position. The rigid, secure fixing of the brackets and, accordingly, the pins is carried out with the help of a tension device. During the operation, the positions of the supports can be changed using the handle 16 and the screw 17.
