Description

Technical Field

[0001] The invention relates to the field of technical medical instruments, and in particular to a deep tissue suturing device. Background Art

[0002] The wound suturing method currently commonly used in surgical operations is to use a suture needle to thread the needle and then tie a knot on the suture. When in use, the suture needs to be inserted into the threading hole of the suture needle, and then the suture needle is clamped with a needle holder for suturing. When the tissue at the site to be sutured is relatively fragile, the suture may cause secondary tearing of the wound during the pulling process; when the wound is small and deep tissue needs to be sutured, the existing suture needle and needle holder have a small operating range and are more difficult to suturing; if the needle holder is not held steadily, the suture needle is likely to fall into the body, bringing great additional risks to the operation. Summary of the invention

[0003] The purpose of the present invention is to provide a deep tissue suturing device to solve the problems of the pulling of the suture thread on the sutured part during the deep tissue suturing process, the secondary suturing operation caused by the suture thread falling off, and the additional surgical risks caused by the suture needle falling into the body.

[0012] The following is a further detailed description of a deep tissue suturing device of the present invention in conjunction with the specific embodiments shown in the accompanying drawings: BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the present invention;

[0014] Figure 2 It is a schematic diagram of the structure of the threading hole and the roller in the present invention;

[0015] Figure 3 It is a schematic diagram of the structure of the roller in the present invention. DETAILED DESCRIPTION

[0016] First of all, it should be explained that the directional words such as up, down, front, back, left and right described in the present invention are only described according to the drawings for the convenience of understanding, and are not intended to limit the technical solution of the present invention and the scope of protection requested.

[0017] like Figure 1 and Figure 2 As shown, an embodiment of a deep tissue suturing device of the present invention comprises a handle 1, a needle body 2 and a needle tip 3. A threading hole 11 penetrating the handle 1 is arranged along the length direction of the handle 1, and a roller 4 is rotatably installed in the handle 1, so that one side of the roller 4 is exposed from the handle 1 and the other side is located in the threading hole 11. The needle body 2 is arranged at the lower end of the handle 1 and corresponds to the threading hole 11, and the needle tip 3 is arranged at the lower end of the needle body 2. The needle body 2 and the needle tip 3 are both hollow structures, and the roller 4 can deliver the suture thread entering the threading hole 11 to the needle tip 3 and pass it out.

[0018] During the actual suturing, first fold the suture in half, let the folded end enter from the entrance of the threading hole 11, use the roller 4 to send the suture through the needle body 2 to the needle tip 3, then after the needle tip 3 passes through the part to be sutured, use the roller 4 to send the suture out of the needle tip 3 (the roller rotates counterclockwise during the specific operation), then pinch one of the sutures at the entrance of the threading hole, use the grasping forceps to grab the suture exposed from the needle tip 3, withdraw the needle tip 3, and finally tie the suture to complete the suturing. Through the above settings, a deep tissue suturing device with a simple structure, flexible operation and reduced suturing time can be formed. During the suturing process, the suture is sent into the part to be sutured through the needle tip 3, which effectively solves the problem of the suture pulling the suture on the suture part during the suturing process; the suture is grabbed by the grasping forceps during the withdrawal of the needle tip 3, thereby preventing the secondary suturing operation caused by the suture falling off; the needle tip 3 is set at the lower end of the needle body 2 to avoid the additional surgical risk caused by the needle tip 3 falling into the body, and the flexible use can reduce the difficulty of the suture operation and reduce the suture time.

[0019] As an optimization solution, Figure 1 and Figure 2 As shown, in order to facilitate the arrangement of the suture thread in the threading hole 11, in the present embodiment, the upper half of the threading hole 11 is offset to the right (i.e., the upper half of the threading hole 11 is offset to the right relative to the axis of the handle 1), and the middle portion of the threading hole 11 is set to a C-shaped structure, the outer peripheral wall on the other side of the roller 4 is located in the C-shaped structure of the threading hole 11 (i.e., the middle C-shaped structure of the threading hole 11 is open, and the outer peripheral wall on the other side of the roller 4 is located at this open position), and the lower half of the threading hole 11 is offset to the left (i.e., the lower half of the threading hole 11 is offset to the left relative to the axis of the handle 1). By setting the above structure, when the suture thread enters the middle part of the threading hole from the upper half, the thread end of the suture thread just falls on the left position just above the arc surface of the roller 4, so that when the roller 4 rotates counterclockwise, the thread end is just pushed to the left, and the suture thread is guided to the C-shaped structure in the middle part of the threading hole 11. When the suture thread moves from the middle part of the threading hole 11 to its lower half, since the lower half of the threading hole 11 is offset to the left, the suture thread can enter the lower half of the threading hole 11.

[0020] As a further improvement, the axial cross-sectional shape of the upper end of the upper half of the threading hole 11 is set to an inverted trapezoid (that is, the aperture of the upper end of the upper half of the threading hole 11 gradually decreases from top to bottom), which is used to quickly insert the thread end of the suture into the threading hole 11. In order to further facilitate the arrangement of the suture in the threading hole 11, the aperture of the connection between the upper half and the middle part of the threading hole 11 is gradually enlarged and then gradually reduced, and the aperture of the connection between the lower half and the middle part of the threading hole 11 is gradually enlarged and then gradually reduced. Through the above settings, the inner wall of the connection between the upper half and the middle part, and the lower half and the middle part of the threading hole 11 can form a smooth curved surface. In this way, when the suture enters these two positions, the smooth curved surface of the inner wall of the threading hole will guide the suture, which is more convenient for the arrangement of the suture and avoids the problem of thread jamming.

[0021] As an optimization solution, Figure 3 As shown, the thickness of the roller 4 in this embodiment is greater than the aperture of the threading hole 11, and an annular protrusion 41 is provided in the middle of the outer peripheral wall of the roller 4. The width of the annular protrusion 41 is adapted to the aperture of the threading hole 11, and the annular protrusion 41 is located in the threading hole 11. The outer peripheral wall of the annular protrusion 41 is provided with corrugated notches along the circumferential direction, so that the friction force applied by the roller 4 on the suture thread is increased, thereby facilitating the driving of the suture thread.

[0022] As an optimization solution, Figure 1 As shown, the needle tip 3 of the present embodiment is connected to the needle body 2 via an adapter 5. The adapter 5 is a tubular structure. The adapter 5 is fixed to the lower end of the needle body 2 via a threaded connection. One end of the needle tip 3 (i.e., the non-puncture end) is fixed to the adapter 5 via a threaded connection. The adapter 5 can be used to replace needle tips of different lengths and models according to actual needs.

[0023] It should be noted that the needle tip 3 in the present invention is a hook-shaped structure, and the other end of the needle tip 3 (i.e., the puncture end) is provided with an inclined cut 31, which is conducive to puncturing the desired suture tissue and reducing damage to the tissue. The upper end of the handle 1 in the present invention is provided with a dust plug 6 that matches the threading hole 11. The dust plug 6 is removed when in use, and the dust plug 6 is reinstalled after use to prevent dust. In order to facilitate holding, an anti-slip protrusion 12 can be provided on the outer peripheral wall of the handle 1, or the outer surface of the handle 1 can be roughened.

[0024] The above embodiments are only descriptions of the preferred embodiments of the present invention, and are not limitations on the scope of protection requested by the present invention. Without departing from the design spirit of the present invention, various forms of deformation made by engineers and technicians in this field based on the technical solution of the present invention should fall within the scope of protection determined by the claims of the present invention.
