Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, and specifically discloses a surgical nail remover. Background Technology

[0002] Surgical skin staples are commonly used to suture surgical incisions or wounds with smooth edges. Compared to needle and suture, they have the advantage of shortening the operation time, greatly reducing the time required for suturing, reducing patient bleeding, reducing tissue damage, and allowing for faster removal of skin staples after surgery. There are special staple removers for removing staples, which are fast, less painful, and do not cause suture knot reaction.

[0003] The existing staple removers used in clinical practice are shaped like scissors. The principle is to bend the middle part of the staple downwards, causing the two sides of the staple to curl up and detach the hooked parts from the skin tissue, which is then removed by medical staff. However, during the use of existing staple removers, the removed staples often stick to the remover. Therefore, when medical staff put the staples into the medical waste bin, they need to shake the remover lightly, which may cause the staples to fall to the ground. Picking up the staples from the ground may also cut their fingers. Utility Model Content

[0004] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0005] A surgical staple remover includes a handle A, a handle B, and a rivet. The front end of handle A has a cutting groove dividing it into two equal-sized parts. Rivet slots are located on both sides of the bottom of the cutting groove. A positioning slot is located in the middle of handle B. The rivet passes through the rivet slots and the positioning slot, connecting handle A and handle B and allowing handle B to rotate around the rivet as its center point. The front end of handle A has a staple-lifting structure consisting of two metal structures fixedly connected to the front end of handle A. The staple-lifting structure is a stepped structure with a smaller front end and a larger rear end. The bottom of the front end of handle B has a rivet pressing block, which is a trapezoidal structure with a larger top and a smaller bottom. Finger sleeves are located at the ends of both handle A and handle B.

[0006] A nail ejection structure is provided between the two nail-raising structures. The nail ejection structure includes a base, several springs, and a lifting plate. The base is fixed to the bottom side of the nail-raising structure, the bottom of the spring is fixed to the base, and the bottom of the lifting plate is connected to the top of the spring.

[0007] Preferably, a return spring is provided between handle A and handle B, and the return spring is located between the rivet and the finger sleeve.

[0008] Preferably, the inner sides of the two nail-raising structures are provided with sliding grooves, and the lifting plate is provided with limiting sliders on both sides. The limiting sliders are located in the sliding grooves and can slide up and down in the sliding grooves.

[0009] Preferably, the bottom of the tack pressing block is provided with an anti-slip groove.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting a skin nail pop-out structure between the nail-removing structures, the skin nails stuck to the remover can be popped out through the skin nail pop-out structure, which can avoid the problem of having to shake the remover to remove the skin nails when they are stuck to it.

[0012] 2. By setting a sliding groove on the inside of the nail-raising structure and setting limiting sliders on both sides of the lifting plate, the sliding cooperation of the sliding groove and the limiting slider can limit the popping direction of the nail popping structure, so that the popping direction is fixed and avoids the popping direction from being skewed, causing the nail to be popped to the ground.

[0013] 3. Anti-slip grooves are provided at the bottom of the tack press block to prevent slippage when removing the tack. Attached Figure Description

[0025] Example 1

[0026] Reference Figure 1-3 A surgical staple remover includes a handle A1, a handle B2, and a rivet 3. The front end of the handle A1 is provided with a cutting groove 1-1, which divides the front end of the handle A1 into two parts of the same size. The bottom sides of the cutting groove 1-1 are provided with rivet slots 1-2. The middle of the handle B2 is provided with a positioning slot 2-1. The rivet 3 passes through the rivet slots 1-2 and the positioning slots 2-1 respectively to connect the handle A1 and the handle B2, and allows the handle B2 to rotate with the rivet 3 as the midpoint. The front end of the handle A1 is provided with a staple lifting structure 4, which consists of two metal structures fixedly connected to the front end of the handle A1. The staple lifting structure 4 is a stepped structure with a smaller front end and a larger rear end. The bottom of the front end of the handle B2 is provided with a rivet pressing block 5, which is a trapezoidal structure with a larger top and a smaller bottom. Both the handle A1 and the handle B2 are provided with finger sleeves 6.

[0027] A nail ejection structure 7 is provided between the two nail-raising structures 4. The nail ejection structure 7 includes a base 7-1, several springs 7-2 and a lifting plate 7-3. The base 7-1 is fixed to the bottom side of the nail-raising structure 4, the bottom of the springs 7-2 is fixed on the base 7-1, and the bottom of the lifting plate 7-3 is connected to the top of the springs 7-2.

[0028] Preferably, a return spring 8 is provided between handle A1 and handle B2, and the return spring 8 is located between rivet 3 and finger sleeve 6.

[0029] In actual operation, first insert the nail-raising structure 4 at the front end of handle A1 into the gap at the bottom of the skin nail, and then press the finger sleeve 6 at the end of handle A1 and handle B2 at the same time, so that the skin nail pressing block 5 at the front end of handle B2 pushes the skin nail downward, causing the skin nail to bend downward in the middle and curl up on both sides. During this process, the skin nail will overcome the elastic force of spring 7-2 and push the lifting plate 7-3 downward under the push of the skin nail pressing block 5.

[0030] Next, remove the skin staple from the wound, then position the staple remover directly in front of the medical waste box, and release the pressure applied to the finger sleeve 6. At this point, under the action of the return spring 8, the handle B2 and the front end of the handle A1 of the staple remover separate, and the lifting plate 7-3, under the action of the spring 7-2, pops the skin staple off the staple removal structure 4, causing it to fall into the medical waste box.

[0031] Example 2

[0032] Reference Figure 4 The difference between this embodiment and the first embodiment is that the inner sides of the two nail-raising structures 4 are provided with sliding grooves 4-1, and the lifting plates 7-3 are provided with limiting sliders 10 on both sides. The limiting sliders 10 are located in the sliding grooves 4-1 and can slide up and down in the sliding grooves 4-1.

[0033] By setting the slide 4-1 and the limiting slider 10, the up and down movement direction of the lifting plate 7-3 is kept consistent, ensuring that the skin nail will not be bounced to the ground due to the change in the ejection direction of the lifting plate 7-3 during the ejection process.

[0034] Example 3

[0035] Reference Figure 5 This embodiment is designed to solve the problem of slippage that may occur during nail removal in Embodiment 1, and provides the following technical solution: an anti-slip groove 5-1 is provided at the bottom of the nail pressing block 5.
