Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a biopsy and skin nailing device. Background Art

[0002] In human surgical operations, epidermal wounds are conventionally sutured manually using various sutures. This traditional suturing method not only takes a long time, but also because the suture depth depends entirely on the operator's manual operation, the suture depth on both sides of the wound is often not completely consistent, resulting in a slight deviation in the apposition of the cortex, which leads to a relatively wide and unsightly scar after the wound heals. Therefore, a skin stapler that uses metal U-shaped staples to staple epidermal wounds was invented by drawing on the principle of a stapler. This skin stapler mechanically staples epidermal wounds manually, with consistent suture depth, accurate alignment of the skin edges on both sides, small and beautiful scars after the wound heals, and a short suturing process, so it is widely used.

[0003] The existing skin stapling machine has a single function and can only suture the cut skin. During the biopsy process, a separate circumcision knife is required to take skin samples. The skin stapling and biopsy skin sampling are separated, which is not convenient for carrying and storage. In view of this, we propose a biopsy and skin stapling device. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: See Figure 1-6The utility model provides a technical solution: a biopsy and skin stapling device, which is mainly aimed at the existing skin stapling machine, which has a single function and can only suture the skin after cutting. During the biopsy process, a separate circumcision tool is required to take skin samples. The problem that the skin stapling and biopsy skin sampling are separated and inconvenient to carry and store is improved. The specific scheme is as follows: It includes a protective shell 1, wherein the material of the protective shell 1 is engineering plastic, which has certain toughness and plasticity and can meet the use requirements of the skin stapling machine.

[0020] See also Figure 1 and Figure 2 A driving assembly 2 and an operating wrench 3 for skin suturing are respectively provided at the upper left and right ends of the protective shell 1, wherein the driving assembly 2 can drive the components inside the protective shell 1, thereby realizing the skin suturing operation on the patient's skin.

[0021] Specifically, the trigger component of the driving assembly 2 is arranged below the operating wrench 3, and the operating wrench 3 is in active contact with the trigger component. The operating wrench 3 is hinged to the protective housing 1, and a biopsy knife 5 is arranged below the operating wrench 3. The biopsy knife 5 is hinged to the protective housing 1, and the biopsy knife 5 can perform a skin removal operation on the skin of the person to be biopsied.

[0022] like Figure 1 As shown, the biopsy knife 5 includes a skin-cutting knife 50, and the material of the skin-cutting knife 50 is a medical knife material. A cutting notch 52 is provided at one end of the skin-cutting knife 50 away from the protective shell 1. The setting of the cutting notch 52 can make the biopsy knife 5 cut in a circular motion along the trajectory of the cutting notch 52 when the biopsy knife 5 performs a circular cutting operation, which is different from the existing circular cutting knife, which only has a circular trajectory after cutting, and it is necessary to use tweezers to remove the skin tissue adhered after the skin is cut, which is troublesome and laborious, and the efficiency of skin biopsy is low.

[0023] Furthermore, a snap-in slot 51 is provided on the skin-removing tool 50, and the skin-removing tool 50 is hinged on the protective housing 1. The snap-in slot 51 can facilitate the snap-in operation of the corresponding connecting component. In order to facilitate the snap-in slot 51 provided on the skin-removing tool 50, a "U"-shaped block can be partially welded on the corresponding side of the snap-in slot 51, wherein the "U"-shaped slot is the snap-in slot 51. For details, see Figure 6 .

[0024] See also Figure 1 , Figure 3 and Figure 4 , wherein a limiting assembly 4 for limiting the position of the biopsy knife 5 is fixedly mounted on the protective housing 1. The limiting assembly 4 can limit the position of the biopsy knife 5, so that it can be stably placed inside the protective housing 1 when not in use.

[0025] Specifically, the limit assembly 4 includes a limit rod 40, and the protective housing 1 is provided with a "T"-shaped slot for inserting the limit rod 40. The limit rod 40 is movably inserted into the protective housing 1, and a return spring 41 is movably sleeved on the limit rod 40. A limit block 42 is fixedly installed on the inner end of the adjacent limit rod 40, and the limit block 42 is movably engaged in the inside of the engagement slot 51. The limit block 42 is "L"-shaped, and the upper end surface of the limit block 42 is provided with an inclined surface inclined to the outside. When the biopsy knife 5 is inserted into the protective shell 1, the clamping force of the biopsy knife 5 can stretch the reset spring 41 and reduce the distance between adjacent limit blocks 42. As the biopsy knife 5 continues to be clamped, when the upper and lower positions of the limit blocks 42 correspond to the clamping slot 51, the limit blocks 42 are clamped into the clamping slot 51 through the setting of the reset spring 41. This can effectively limit the position of the biopsy knife 5, facilitate the storage of the biopsy knife 5, and increase the functionality of the skin nailing machine.

[0026] The working principle of the present application is as follows: when performing a biopsy operation, first, the limiting rods 40 on both sides are squeezed inward to stretch the reset springs 41. At this time, the spacing between adjacent limiting rods 40 is reduced, so that the limiting clamping block 42 can be disengaged from the inside of the clamping slot 51 on the biopsy knife 5, and the biopsy knife 5 is folded clockwise. By operating the biopsy knife 5, the patient's skin removal position can be circumcised; during the skin cutting process, the biopsy knife 5 cuts along the trajectory of the cutting slot 52 in a circular motion, which is different from the existing circumcision knife, which only has a circular trajectory after cutting, and it is necessary to use additional tweezers to remove the skin tissue adhered after skin removal, which is troublesome and laborious, and the efficiency of skin biopsy is low. The problem is that the biopsy skin removal operation can be completed at one time, which speeds up the efficiency of the biopsy. After the skin removal is completed, the operating wrench 3 is folded counterclockwise to clamp the biopsy knife 5 into the protective shell 1. During this process, as the biopsy knife 5 continues to be clamped, when the upper and lower positions of the limit clamp block 42 and the clamping slot 51 correspond, the limit clamp block 42 is clamped into the clamping slot 51 through the setting of the reset spring 41, which can effectively limit the position of the biopsy knife 5. The driving component 2 can make the skin nailing component suture the incision after cutting. Both the biopsy skin removal and the skin nailing can be used separately, which is easy to store and can effectively avoid the occurrence of loss, further improving the efficiency of the biopsy.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
