The suture needle 100 of the utility model is used for suturing urethra and bladder via urethra, compared with the suture operation of bladder and urethra in abdominal cavity, the suture needle 100 of the utility model is more convenient for suturing bladder and urethra, during the suture operation of the bladder and the urethra, the driving rod 31 of the driving member 30 is moved relative to the housing 10 along the axial direction of the housing 10 by the external force, because one end of the switching rod 40 is pivoted with the driving rod 31, the other end of the switching rod 40 is pivoted with the needle tail 22 of the sewing needle 20, the needle 20 is pivotally connected to the housing 10 at a position between the needle head 21 and the needle tail 22, so that when the driving rod 31 of the driving member 30 moves relative to the housing 10 along the axial direction of the housing 10, the adapter rod 40 moves along the radial direction of the housing 10, so as to drive the suture needle 20 to swing relative to the housing 10, and further, the suture needle 20 can suture the bladder and the urethra by reciprocating swing.
It should be noted that, when the suture needle 100 is used for suturing the urethra and the cysts via the urethra, it is necessary to precisely control the swing angle of the needle 20 of the suture needle 100, the swing angle of the needle 20 is related to the distance of the axial movement of the driving rod 31 along the housing 10, in order to precisely control the swing angle of the needle 20 of the suture needle 100, in some embodiments of the present invention, referring to fig. 1, the peripheral wall of the housing 10 away from the open end thereof is provided with an avoiding opening 11 extending along the axial direction of the housing 10, the driving member 30 further includes a rack 32 and a gear 33, the rack 32 is mounted on the inner wall surface of the housing 10 and extends along the axial direction of the housing 10, the gear 33 is pivotally connected to the driving rod 31, and the gear 33 is meshed with the rack 32. Because the distance between adjacent teeth on the rack 32 is fixed, when the driving rod 31 moves relative to the housing 10 along the axial direction of the housing 10, the distance of the axial movement of the driving rod 31 along the housing 10 can be controlled by controlling the relative position of the gear 33 and the rack 32, and the avoidance opening 11 can be used for a user to directly or indirectly contact the driving rod 31 to exert force on the driving rod 31, so that the driving rod 31 moves along the axial direction of the housing 10, and the swing angle of the sewing needle 20 can be accurately controlled, thereby facilitating the sewing operation of the bladder and the urethra.
Further, the outer peripheral wall of the driving rod 31 is protruded with a protrusion 311 protruding out of the avoiding opening 11, and the protrusion 311 may serve as a force bearing point, which allows a user to drive the driving rod 31 to move along the axial direction of the housing 10 by applying an external force to the protrusion 311.
Further, the protrusion 311 is matched with the avoiding opening 11, so that the protrusion 311 can be used as a force bearing point, and the protrusion 311 can also play a role in guiding, thereby ensuring the movement direction of the driving rod 31 and avoiding the problem that the driving rod 31 rotates along the circumferential direction of the housing 10.
Further, the outer shell 10 is protruded outward relative to the outer peripheral wall of the avoiding opening 11 to form a holding portion 12 for a user to hold, and the arrangement of the holding portion 12 increases the contact area between the outer shell 10 and the user, which is convenient for the user to hold the outer shell 10, and further convenient for the user to use the suture needle 100.
In order to precisely control the swing angle of the needle 20 of the suturing needle 100, in another embodiment of the present invention, referring to fig. 2, one end of the housing 10 away from the needle 20 is open; the driving member 30 further comprises an adjusting knob 34, the adjusting knob 34 is connected to an end of the housing 10 away from the needle 20 and can rotate freely relative to the housing 10, and the adjusting knob 34 is in threaded connection with an end of the driving rod 31 away from the adapting rod 40. With such an arrangement, the driving rod 31 can be driven to reciprocate along the axial direction of the housing 10 by rotating the adjusting knob 34, so as to achieve the effect of driving the sewing needle 20 to swing back and forth.
Further, referring to fig. 3, an annular protrusion 13 extending along the circumferential direction of the housing 10 is protruded from the inner circumferential wall of the housing 10 at an end away from the needle 20; the adjusting knob 34 is formed in a cylindrical shape with an open end, and an annular groove 341 engaged with the annular protrusion 13 is concavely formed on the outer circumferential wall thereof. So configured, the rotatable connection of the adjustment knob 34 to the housing 10 is achieved.
Of course, the inner peripheral wall of the housing 10 may also be concavely provided with an annular groove extending along the circumferential direction thereof, the outer peripheral wall of the adjusting knob 34 is correspondingly provided with an annular protrusion extending along the circumferential direction thereof, and the fitting of the annular protrusion and the annular groove can enable the adjusting knob 34 to be rotatably connected with the housing 10; the housing 10 and the adjusting knob 34 may be connected by a transfer bearing, an outer ring of the transfer bearing is tightly fitted with an inner circumferential wall of the housing 10, and an inner ring of the transfer bearing is tightly fitted with the adjusting knob 34, so that the adjusting knob 34 can be ensured to rotate relative to the housing 10.
It should be noted that the adjusting knob 34 can be fully or partially extended into the housing 10, and preferably, the adjusting knob 34 is partially extended into the housing 10, and the adjusting knob 34 is partially exposed out of the housing 10, so that the user of the suture needle 100 can directly apply an external force to the portion of the adjusting knob 34 exposed out of the housing 10, thereby facilitating the operation of the suture needle 100.
It should be noted that there are various structures for controlling the distance of the axial movement of the driving rod 31 along the housing 10, which are not necessarily exemplified herein.
In order to avoid the influence of the shell 10 on the swing angle of the sewing needle 20, in some embodiments of the present invention, please refer to fig. 1 or fig. 2, the peripheral wall of the shell 10 adjacent to one end of the sewing needle 20 is provided with two abdicating notches 14 which are oppositely disposed, the two abdicating notches 14 are all provided through the end surface of the shell 10 adjacent to the sewing needle 20, and the two abdicating notches 14 are used for abdicating the sewing needle 20 and the adapter 40. Because the suture needle 20 swings in the plane of the two abdicating notches 14, the arrangement of the two abdicating notches 14 enables the suture needle 20 and the adapter rod 40 to partially extend out of the shell 10, thus ensuring that the swing angle of the suture needle 20 is large enough, and further facilitating the suture operation of the bladder and urethra by using the suture needle 100.
In order to adjust the swing angle of the needle 20, in some embodiments of the present invention, referring to fig. 1 or fig. 2, the distance between the needle end 22 of the needle 20 and the position where the needle 20 and the housing 10 are pivoted is smaller than the distance between the needle head 21 of the needle 20 and the position where the needle 20 and the housing 10 are pivoted. With such an arrangement, only the part of the needle 20 inside the housing 10 needs to rotate by a small angle, and the part of the needle 20 outside the housing 10 can rotate by a large angle, and since the rotation angle of the part of the needle 20 extending into the housing 10 is positively correlated with the distance of the driving rod 31 along the axial movement of the housing 10, the distance of the driving rod 31 along the axial movement of the housing 10 can be shortened, thereby facilitating the control of the angle of the needle 20.
