Reusable medical skin stapler with adjustable force

Abstract

The invention discloses a reusable and intensity-adjustable medical skin stitcher. The reusable and intensity-adjustable medical skin stitcher comprises double sticky tapes, a first base, a second base, a rack, a locking fastener, a tensioner and a fine adjustment nut, wherein the locking fastener has a locked state and an unlocked state, when the locking fastener is in the locked state, the firstbase and the base can be close to each other, and when the locking fastener is in the unlocked state, the first base and the second base can be conveniently disconnected. The reusable and intensity-adjustable medical skin stitcher achieves unlocked separation of the first base and the second base as well as fine adjustment of the fine adjustment nut by changing the double sticky tapes to furtherachieve reusability and force adjustability and controllability, thereby solving the problem that medical skin stitchers in the prior art cannot be disconnected and are non-reusable after being closedonce.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a reusable medical skin stapler with adjustable force. Background technique [0002] The medical skin stapler is a surgical product, which is widely used for incision butt joint and skin suturing in surgical operations, without the need for surgical needles and sutures. The existing medical skin stapler cannot be disassembled after being closed once, and can only be used once. After an operation error, it can only be replaced with a new product, resulting in a waste of resources and an increase in medical costs. Moreover, the existing skin suturing device does not have a strength monitoring mechanism. If the suturing force applied to the wound is too small, it will easily lead to delayed wound healing; and if the suturing force applied to the wound is too large, it will easily cause tension stress to stimulate and damage the skin, resulting in tension in the wound skin Pathologica...

Problems solved by technology

The existing medical skin stapler cannot be disassembled after being closed once, and can only be used once. After an operation error, it can only be replaced with a new product, resulting in a waste of resources and an increase in medical costs.

Moreover, the existing skin suturing device does not have a strength monitoring mechanism. If the suturing force applied to the wound is too small, it will easily lead to delayed wound healing; and if the suturing force applied to the wound is too large, it will easily cause tension stress to stimulate and damage the skin, resulting in tension in the wound skin Pathological damage of sexual vesicles

[0003] The application document with the patent number CN106308860 discloses an adjustable skin wound stapler, which can use tweezers or pliers in the operation to clamp the lock adjustment handle, so that the spines can be retracted, but the patent disclosure is not sufficient , and there is no response to the callback strength monitoring device, which is still adjusted by the experience of medical staff, and there are certain disadvantages in actual use

[0004] The application document with the patent number CN102217960 discloses a skin wound stapler that can promote skin wound healing: a force measuring device for measuring the suture force is arranged between the suturing structures on both sides of the skin wound, but the lateral force device is only The measuring scale with strength marks, the side force is not accurate enough, and the distance to be adjusted according to the side force device is only the distance between two or more ratchets, which is more accurate than the distance between two ratchets The distance adjustment is not possible

[0005] To sum up, in the prior art, there is still a lack of effective solutions to the problem of how to realize the repeated use of medical skin staplers and precisely adjust the suturing strength
