In a first embodiment of the present invention, as shown in fig. 1, a novel incision inner wall tissue stapler comprises a rotary handle 1, a housing 3, a worm 4, a worm wheel 5, a suture needle 6, a worm wheel support bearing 7, a protective housing 8 and a brake lever 10. The rotary handle 1 is mounted at the upper end of the housing 3, one end of the brake lever 10 passes through the interior of the housing 3 and is connected with the rotary handle 1, and the other end of the brake lever 10 is connected with the worm 4. Preferably, the longitudinal axis of the brake lever 10 overlaps the longitudinal axis of the housing 3. The housing 3 is preferably a hollow tubular structure made of silicone.
As shown in FIG. 1, the novel incision inner wall tissue stapler preferably further comprises a rotating assembly support bearing 2, and the rotating assembly support bearing 2 is mounted at the upper end of the housing 3 and is fixed with the rotating handle 1. Preferably, the rotating assembly support bearing 2 may be divided into a first rotating assembly support bearing 21 and a second rotating assembly support bearing 22, and the first rotating assembly support bearing 21 and the second rotating assembly support bearing 22 are symmetrically distributed at both sides of the housing 3, the main functions of which are to reduce the friction coefficient of the rotating handle 1 during the rotating motion and to secure the turning accuracy of the rotating handle 1.
As shown in fig. 1, the worm 4 and the worm wheel 5 are connected together in a matched mode in structure, so that the movement of the worm 4 drives the movement of the worm wheel 5. The number of turbines 5 may be 1 or more. Preferably, the number of turbines 5 is two, namely a first turbine 51 and a second turbine 52, the first turbine 51 and the second turbine 52 being symmetrically distributed on both sides of the worm 4. Preferably, the left side and the right side of the worm 4 are in a zigzag structure, the right side of the first turbine 51 is in a zigzag structure, and the first turbine and the zigzag structure on the left side of the worm 4 are just meshed together; the left side of the second worm wheel 52 is a zigzag structure and just bites together with the zigzag structure on the right side of the worm 4.
As shown in fig. 1 and 2, the turbine support bearing 7 preferably includes a first turbine support bearing 71 and a second turbine support bearing 72, and serves to support the rotation of the turbine 5, specifically, to reduce the coefficient of friction of the turbine 5 during the rotational movement and to ensure the rotational accuracy of the turbine 5. The turbine shaft 9 is vertically mounted on the turbine 5, and the first turbine support bearing 71 and the second turbine support bearing 72 are symmetrically mounted on both sides of the turbine shaft 9. The worm 4 drives the turbine 5 to rotate, the turbine 5 drives the turbine shaft 9 to rotate, and the turbine shaft 9 drives the sewing needle 6 to rotate.
As can be seen from fig. 2 and 3, the needle 6 is located below the housing 3, fixed to the turbine shaft 9, between the turbine 5 and the second turbine support bearing 72, although the needle 6 may be located between the turbine 5 and the first turbine support bearing 71. The suture needle 6 is fixed on the turbine shaft 9 and rotates along with the turbine shaft 9 to complete the suture needle threading action. Furthermore, as shown in fig. 1, the sewing needle 6 may be installed between the worm wheel 5 and the second worm wheel support bearing 72 and between the worm wheel 5 and the first worm wheel support bearing 71, wherein the sewing needle 6 located between the worm wheel 5 and the first worm wheel support bearing 71 is the first sewing needle 61 and the sewing needle 6 located between the worm wheel 5 and the second worm wheel support bearing 72 is the second sewing needle 62. Preferably, the first and second sewing needles 61, 62 are symmetrically distributed along the central axis of the worm gear 5.
As can be seen from fig. 1 and 2, a protective housing 8 is fixed on the outer side of the lower end of the housing 3, and the worm 4, the worm wheel 5, the first worm wheel support bearing 71, the second worm wheel support bearing 72, the worm wheel shaft 9 and the sewing needle 6 are located inside the protective housing 8. The protective housing 8 serves to protect the worm 4, the worm wheel 5, the first worm wheel support bearing 71, the second worm wheel support bearing 72, the worm wheel shaft 9 and the suture needle 6, and the presence of the protective housing 8 prevents the suture needle 6 from scratching human tissues when suturing is performed. As shown in fig. 4, to ensure that the needle 6 is able to perform a rotational movement, both opposite sides of the protective housing 8 are provided with notches 81, thereby allowing the needle 6 to suture incision tissue through the notches 81 when rotated. Of course, when the number of the suture needles 6 is 2 (i.e., the first suture needle 61 and the second suture needle 62 exist at the same time), the number of the notches existing at the two opposite sides of the protective case 8 increases accordingly, and the positions where the notches exist correspond to the positions where the first suture needle 61 and the second suture needle 62 exist. Preferably, the needle 6 (first needle 61 and second needle 62, if present at the same time) is arcuate, more preferably, the needle 6 (first needle 61 and second needle 62, if present at the same time) is semi-circular.
Before suturing, the suture thread is threaded onto the suture needle 6 (the first suture needle 61 and the second suture needle 62, if present at the same time). After the suture thread is threaded, the rotary handle 1 is rotated, so that the rotation motion of the rotary handle 1 can be converted into the rotation motion of the suture needle 6 (the first suture needle 61 and the second suture needle 62 if the suture thread exists at the same time) by utilizing the turbine worm transmission principle, and the motion conversion between different axes and different planes is completed. Specifically, the rotary handle 1 rotates around a Y axis 91 (in fig. 1, the Y axis 91 is the axial axis of the rotary handle 1) in fig. 1 (in which the X axis 90 is not shown), and the rotary handle is converted into a turbine 5 through a turbine worm transmission to rotate around a Z axis 92 in fig. 2 (in which the X axis 90 is not shown), so as to drive the suture needle to rotate around the Z axis 92, and the suture action of the suture needle 6 in the wound tissue is completed.
In another embodiment of the present invention, as shown in fig. 5, the incision inner wall tissue stapler includes a brake knob 31, a housing 32, a brake lever 33, a needle 34, and a protective case 35, the brake knob 31 is installed at an upper end of the housing 32, one end of the brake lever 33 is coupled to the brake knob 31 through an inside of the housing 32, and the other end of the brake lever 33 is coupled to the needle 34 located under the housing 32.
As shown in fig. 5, preferably, the brake lever 33 includes a first brake lever 331 and a second brake lever 332, and the suture needle 34 includes a first suture needle 341 and a second suture needle 342, wherein the first brake lever 331 is connected to the first suture needle 341, and the second brake lever 332 is connected to the second suture needle 342. The suture needle 34 is located inside a protective housing 35, and the protective housing 35 serves to protect the suture needle 34. The two opposite sides of the protective housing 35 have notches 81 (similar to the notch arrangement of fig. 4) through which the suture needle 34 passes when rotated to suture the incision tissue 36 when suturing.
When the suture is performed, the brake knob 31 is operated to rotate, the brake knob 31 drives the brake rod 33 to move, and the suture needle 34 is driven to rotate, so that the suture needle 34 can complete the task of suturing the incision tissue 36.
In another embodiment of the invention, the brake knob 31 of fig. 5 can be replaced by the rotary knob 1 of fig. 1, in which case the rotary knob is connected to a brake lever 33 arranged inside the housing 32, the others remaining unchanged.
In another embodiment of the invention, the rotary knob 1 of fig. 1 can be replaced by a brake knob 31 of fig. 5, which is then connected to a brake lever 10 arranged inside a housing 32, the others remaining unchanged.
Regardless of the embodiment of the invention, the suture of the incision tissue can be standardized, and a standardized suture channel is provided for doctors, so that the postoperative suture becomes more convenient and safer, and the occurrence probability of postoperative complications of patients is greatly reduced. At present, similar products are not available in the market.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
