Description

Wound suturing device

(I) technical field

The invention relates to the technical field of medical instruments, in particular to a wound suturing device.

(II) background of the invention

The depth of a wound of a medical operation cannot be known by an original curved needle suture method, and suture devices in the market adopt oblique needle insertion along an inner channel, and the whole wound is not punctured through the whole skin (partial tissues are punctured through the channel flow only obliquely) when the needle is inserted, so that the thread hooked by the needle is not the suture penetrated through the whole skin.

Disclosure of the invention

The present invention is directed to a wound closure device that solves the problems of the prior art, such as the inability to know the depth and the inability to close the wound through the entire skin.

In order to solve the technical problems, the invention adopts the technical scheme that:

a wound suturing device comprises a main body and wings, wherein the wings are arranged at the lower end of the main body and are arranged in pairs, and a linkage mechanism is arranged inside the main body and can control the opening and closing of the wings. The spreading fin is provided with a second lead-in hole, and the main body is provided with a first lead-in hole. The first leading-in hole and the second leading-in hole can be internally provided with a side groove needle or a trocar. The suture needle can penetrate the suture line sequentially through the two leading-in holes on the suture device to complete the suture.

In the novel embodiment, a main shaft arranged in the main body is used as a linkage mechanism, and the purpose of controlling the opening and closing of the wings is achieved through the movement of the main shaft. Of course, the linkage mechanism may also be controlled by multiple shafts together or by using a push rod mechanism or the like to accomplish this.

In a specific embodiment of the invention, a aiming hoop is sleeved on the main body, and a third lead-in hole is arranged on the aiming hoop.

In a specific embodiment of the present invention, the centers of the first introduction hole, the third introduction hole and the second introduction hole when the fins are opened are on the same straight line.

Preferably, a connecting line between the circle center of the first introduction hole and the circle center of the second introduction hole when the spreading fin is opened is parallel to the central axis of the main body.

Preferably, a track is provided along the axial direction of the body, along which the aiming collar is slidable.

Preferably, the rail is a convex rail or a concave rail, and the upper surface of the rail is provided with a limit cross striation.

Preferably, a fixture block is arranged on the aiming hoop and plays a role in limiting the position of the aiming hoop. The fixture block is connected with a lifting device, and the fixture block can be separated from and fastened on the limiting transverse grains through the tilting and resetting actions.

In an embodiment of the present invention, a positioning rubber pad is installed in the second guiding hole.

In a specific embodiment of the present invention, a suture needle is provided through the first and second introduction holes.

Preferably, a stop device may be provided at the top of the needle. Therefore, after the suture needle passes through the first introduction hole and the second introduction hole, the limiting device can limit the puncture depth of the suture needle into the skin during needle insertion, and the pointed end of the suture needle is controlled to just penetrate through the positioning rubber pad arranged in the second introduction hole, so that the suture thread can be reserved in the positioning rubber pad, and the suture thread cannot be punctured into the lower layer of the skin too much to cause other injuries of a patient.

Preferably, a groove convenient for fixing the suture line is formed in one side of the suture needle, so that the suture line is convenient to fix, and the suture line is convenient to separate when lifted upwards.

Preferably, the suture needle has a hollow structure, and a suture thread is threaded through the suture needle.

Preferably, the top of main part is installed the rotation lock, the pivot is installed to the top of rotation lock the top of pivot install the handle.

Preferably, barbs are provided on the suture.

In an embodiment of the invention, a traction channel is arranged in the first introduction hole, and the traction channel can enable the suture needle passing through the first introduction hole to accurately pass through the second introduction hole.

Compared with the prior art, the invention has the following beneficial effects:

the invention is provided with a main body, a main shaft and an aiming hoop, when a user needs to suture a patient, the device is inserted into the wound of the patient, a handle is moved or rotated, the handle drives the connected main shaft to horizontally open the wings left and right, the handle is twisted to rotate the rotating lock, the rotating lock is in a locking state to fix the positions of the wings, the main body is lifted up to enable a positioning adhesive to be close to the inner wall of subcutaneous tissue, the aiming hoop is moved downwards on a track, the aiming hoop is limited by a clamping block after being close to the outer skin, so that the aiming hoop is fixed, the skin tissue of the patient is clamped by the aiming hoop and the unfolded wings, the depth of the wound of the patient can be known, the needle can be accurately inserted, and the suturing efficiency is improved.

When a user needs to perform a suturing operation, the suture is placed into a trocar or a side groove needle, the trocar or the side groove needle with the suture passes through the first introduction hole at the upper end of the main body, penetrates into the third introduction hole in the aiming hoop at the lower end of the main body, finally penetrates through a skin layer on one side of a wound and penetrates into the positioning rubber pad in the second introduction hole, the suture is embedded into the positioning rubber pad on the second introduction hole, the trocar or the side groove needle is lifted, the trocar or the side groove needle is separated from the positioning rubber pad of the second introduction hole and is separated from the skin, but the suture embedded into the positioning rubber pad is retained in the positioning rubber pad due to the adhesive force of silica gel, the needle descending and lifting operation is repeated on the other side of the wound with the suture or the other side of the side groove, the locking device is released, the handle is moved or rotated, the main shaft connected with the handle is folded, the positioning rubber pad at the bottom of the main body is slightly lifted, the positioning rubber pad is lifted, the suture needle descending and lifting operation needle is repeatedly lifted from the trocar or the side groove needle, the needle lifting operation is repeatedly lifted, the suture needle descending and lifting operation is further performed, the suture needle is performed, the suture needle lifting operation is performed, the suture needle lifting handle is performed, the suture lifting operation is performed, the suture needle lifting handle.

After the suture is punctured through the positioning glue along with the needle, the barb on the suture also penetrates through the positioning glue or is embedded into the positioning glue in the puncturing process, so that the stable embedded connection of the suture and the positioning glue is formed. When the needle is lifted upwards, the wings are folded and spread, the main body is lifted and the like, the possibility that the suture line is mistakenly pulled out from the positioning rubber is greatly reduced due to the stable embedded connection of the barbs and the positioning rubber pad.

The existence of the traction channel can ensure that the suture needle passing through the first lead-in hole can accurately pass through the second lead-in hole, and the deviation is prevented when the needle is inserted.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
