Description
Technical Field
The invention relates to a skin anastomat convenient to operate, and belongs to the technical field of medical instruments.
Background
The skin anastomat is a device which inserts suturing nails into two sides of a skin wound to achieve the effect of suturing the skin. The skin anastomat is used for occluding the skin on two sides of a wound by a dental disc carried by the instrument, and a nail pushing device pushes a suturing nail out of a nail bin and suturing the skin of the wound along the direction parallel to the inner surface of the wound. Before the existing skin anastomat is used, auxiliary instruments such as tweezers need to be used for lifting epidermal tissues on two sides of a wound to be sutured, so that a dental tray can successfully bite the skin on two sides of the wound. The prior Chinese patent No. 201520318196.9, named as an absorbable nail subcutaneous suture instrument, discloses an absorbable nail subcutaneous suture instrument, which comprises a shell, a nail pushing device, a transmission device, a nail bin, a nail discharging device and a suture nail, and has the advantages that the suture nail can be pushed out along the direction parallel to the surface of a wound to be sutured and is sutured under the skin epidermis, namely, the dermis layer is sutured, the skin epidermis tissue is prevented from being injured, and the wound after healing is beautified. It also has the following disadvantages: before each suture, the epidermis tissues on two sides of the wound to be sutured need to be lifted by the tissue forceps, and then the head end of the suture head is embedded into the wound to be sutured, so that the operation is complicated, the workload of operators and the difficulty of operation are increased, and the efficiency of suturing is influenced.
Disclosure of Invention

In the embodiment, when performing the first suture, the operator first uses the tissue forceps to lift the epidermis tissues at the two sides of the wound to be sutured, embeds the head end of the anastomat into the wound to be sutured, keeps the push-out direction of the suture nail in the anastomat parallel to the surface of the sutured tissue, controls the two occlusion cranksets 6 to rotate around the root parts of the two occlusion cranks to switch from the open state to the closed state, in the process, the two clamping bulges 7 are matched with each other to clamp the epidermal tissues at the two sides of the upper stitching nail part, the subcutaneous dermal tissue to be sutured is sent into a suturing area 5, the sliding needle 4 is controlled to move along the sliding sleeve 3 to push out suturing nails positioned in the sliding sleeve 3 along the direction parallel to the surface of a wound to be sutured, horizontally suturing the hypodermis of the surface of the wound to be sutured, and vertically lifting the anastomat from the wound after suturing to finish the first suturing; when subsequent suturing is carried out, the head end of the anastomat is directly embedded into a wound to be sutured and is adjusted to a proper position, then the two occlusion tooth discs 6 are controlled to rotate by taking the root parts of the two occlusion tooth discs as centers to enable the two occlusion tooth discs to be switched from an open state to a closed state, in the process, the two gathering bulges 8 are mutually matched and used for clamping the epidermal tissues on the two sides of the front side of the upper suturing nail part, meanwhile, the epidermal tissues on the two sides of the upper suturing nail part can be mutually gathered, so that the epidermal tissues on the two sides of the upper suturing nail part can be clamped through the mutual matching of the two clamping bulges 7, the subcutaneous dermal tissues to be sutured are sent into a suturing area, the sliding needle 4 is controlled to be pushed out to complete one-time suturing, and the operations are repeated to complete the subsequent suturing; when the suturing nails in the cartridge 16 are used up, an operator pushes the sliding sleeve 3 to move towards the rear side, then pushes the push button 17 downwards to push the cartridge 16 to move downwards for a certain distance through the push piece 18, so that the bottom end of the cartridge 16 extends out of the bottom opening of the nail bin 15, then the operator can clamp the bottom end of the cartridge 16 through tweezers to take out the bottom end of the cartridge 15, then a new suturing nail is loaded into the cartridge 16, then the cartridge 16 filled with the suturing nail is loaded into the nail bin 15, connection and fixation are realized through the matching between the clamping strip 24 and the clamping groove 25, and then the sliding sleeve 3 is pushed to reset towards the front side.
When the device is used for suturing, only auxiliary instruments such as tweezers and the like are used for clamping during the first suturing, the subsequent suturing operation is convenient, the workload and the operation difficulty of operators can be greatly reduced, the suturing efficiency can be improved, and the operation time can be shortened.
