Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a palm fixing device during surgery. Background Art

[0002] Currently, in trauma surgery on the palm, the injured palm usually needs to be fixed on a board to facilitate the doctor to perform the operation. However, under anesthesia, the fingers will naturally bend, affecting the surgeon's surgical operation on a specific position. Therefore, an assistant is needed to help use a retractor to flatten the palm to make it more convenient for the surgeon to perform the operation and to have a better surgical field of view.

[0003] The conventional practice is to use a fixing plate, install nails on the side of the fixing plate, wrap rubber bands around the nails, and then use the rubber bands to fix the palm placed on the fixing plate. Although the fingers can be effectively fixed, the nails of the fixing plate are exposed when the fixing plate is not in use. When taking the fixing plate, the exposed nails may cause the risk of stabbing the patient or medical staff, or causing bumps and damage to other medical devices. Utility Model Content

[0032] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0033] In one embodiment of the utility model, an intraoperative palm fixation device is provided. When a doctor performs surgery on a patient's hand, the intraoperative palm fixation device can be used to effectively fix the patient's hand to ensure a smooth surgical process.

[0034] like Figure 1-Figure 3 As shown, in an embodiment of the utility model, a palm fixation device during surgery includes a fixing plate 100, and a plurality of receiving grooves 101 are evenly spaced on both side walls of the fixing plate 100; a hanging ring 200 is provided in each connecting cavity 103;

[0035] It also includes rubber bands 300 inserted into a plurality of hanging rings 200 . When the hanging rings 200 extend from the storage slots 101 , the rubber bands 300 are inserted and wrapped around the hanging rings 200 , so as to use the rubber bands 300 to fix the patient's hands placed on the fixing plate 100 .

[0036] Furthermore, in the embodiment of the utility model, an adjustment cavity 102 is also provided in the fixing plate 100, and the adjustment cavity 102 is communicated with the storage groove 101 through a connecting cavity 103; a pulling component is provided in the adjustment cavity 102, and the pulling component is connected to the hanging ring 200 through an elastic member, and the elastic member is provided in the connecting cavity 103.

[0037] When the hanging ring 200 needs to be extended from the fixing plate 100, the pulling assembly is used to release the hanging ring 200, and the hanging ring 200 is pushed out of the receiving groove 101 under the elastic restoring force of the elastic member;

[0038] Correspondingly, such as Figure 5-Figure 7 As shown, when the hanging ring 200 needs to be stored in the storage groove 101, the pulling assembly is used to tighten the hanging ring 200 so that the hanging ring 200 is retracted into the corresponding storage groove 101, and the elastic member is in a compressed state at this time.

[0039] Therefore, when it is necessary to use the intraoperative palm fixation device of the present application, it is only necessary to use the pulling assembly to release the hanging ring 200, so that the hanging ring 200 can be extended from the storage groove 101. For the extended hanging ring 200, it is convenient to insert the rubber band 300 and wrap it around the corresponding hanging ring 200, so as to further use the rubber band 300 to restrain and fix the patient's hand placed on the fixing plate 100.

[0040] Further, such as Figure 3-Figure 6 As shown, the pulling assembly includes an adjusting shaft 402, which is rotatably arranged in the adjusting cavity 102. The pulling assembly also includes a retractable roller 403, which is coaxially fixedly installed on the adjusting shaft 402. When the adjusting shaft 402 rotates, the retractable roller 403 can be driven to rotate synchronously.

[0041] like Figure 4-Figure 6 As shown, the pulling assembly also includes an operating nut 400, on which a screw rod 401 is coaxially fixedly mounted. The operating nut 400 is screwed into the adjusting cavity 102 by a threaded connection. Since the threaded connection structure has a good self-locking effect, when the user manually rotates the operating nut 400, the operating nut 400 can be rotated to a certain angle. Correspondingly, when the user no longer operates the operating nut 400, the operating nut 400 no longer rotates.

[0042] Furthermore, a square rod 404 is coaxially fixedly installed at one end of the adjusting shaft 402, and the screw 401 is axially slidably sleeved on the square rod 404. Since the square rod 404 is a non-circular structure, the screw 401 is sleeved on the square rod 404. When the screw 401 rotates, the adjusting shaft 402 is synchronously driven to rotate without affecting the movement of the screw 401 relative to the adjusting shaft 402.

[0043] Please continue reading Figure 4 In the embodiment of the utility model, the elastic member includes a support rod 201, the support rod 201 is slidably disposed in the connecting cavity 103, the hanging ring 200 is fixedly mounted on one end of the support rod 201, and the other end of the support rod 201 is connected to a pull rope 202, and the pull rope 202 is wound around the retracting roller 403;

[0044] Furthermore, a guide block 500 is fixedly provided at the connection point between the connecting chamber 103 and the adjusting chamber 102. The guide block 500 is connected to the support rod 201 via a connecting spring 203. When the retracting roller 403 rotates, the pull rope 202 can be retracted to pull the support rod 201 to move in the connecting chamber 103, thereby pulling the hanging ring 200 into the storage groove 101. Correspondingly, when the retracting roller 403 releases the connecting spring 203, the pull rope 202 is pushed out of the storage groove 101 under the elastic reset support of the connecting spring 203.

[0045] like Figure 6 As shown, for the same retractable roller 403, it is necessary to reel in the connecting springs 203 on both sides simultaneously. In a specific implementation, the two connecting springs 203 on both sides of the retractable roller 403 are wound around the retractable roller 403 in the same direction. When the retractable roller 403 rotates, the two connecting springs 203 can be reeled in simultaneously, and correspondingly, the two connecting springs 203 can also be released.

[0046] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described here.
