Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a new type of hand-controlled instrument for endoscopes. Background Art

[0002] The new type of hand-controlled instrument for endoscopes is a kind of high-precision surgical instrument designed specifically for endoscopic surgeries. Through a hand-controlled manner, doctors can more flexibly control the surgical instrument during the operation, achieving delicate surgical operations.

[0003] Generally, a reverse force needs to be applied to the guide rod to achieve the rotation of the front-end jaw. Since the hand-controlled instrument for endoscopes needs to be inserted into the human body, while applying the reverse force, the jaws will also move along with this reverse force, and it cannot be guaranteed that the movement of the jaws will not cause harm to the human body, increasing the risk. Therefore, it is necessary to improve this situation. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides the following technical solutions:

Detailed implementation mode

[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a hand-held instrument for a new type of endoscope, including;

[0026] A holding part 1, a connecting part 2, and a front end part 3 connected in sequence, and the holding part 1 is drivingly connected to the front end part 3 through the connecting part 2;

[0027] An adjusting and rotating assembly 4 fixed to the connecting part 2, and the adjusting and rotating assembly 4 includes; a cross turntable 41 and at least four groups of guide holes 46;

[0028] The cross turntable 41 is installed in the inner cavity of the connecting part 2, and a rotatable first wire winding wheel 44 and a second wire winding wheel 45 are arranged on the outer side of the cross turntable 41. A second steel wire rope 48 is wound around the first wire winding wheel 44, and a third steel wire rope 49 is wound around the second wire winding wheel 45;

[0029] The guide holes 46 penetrate through the connecting part 2 and the front end part 3. The ends of the second steel wire rope 48 and the third steel wire rope 49 far from the connecting part 2 pass through two of the guide holes 46, and are threaded back through the adjacent two other guide holes 46 and wound around the first wire winding wheel 44 and the second wire winding wheel 45.

[0030] The operator rotates the first wire winding wheel 44 and the second wire winding wheel 45 to make the second steel wire rope 48 and the third steel wire rope 49 tighten and loosen, so as to drive the front end part 3 to rotate by the second steel wire rope 48 and the third steel wire rope 49. There is no need for the operator to apply a reverse force to realize the rotation of the front end part 3, preventing the front end part 3 from moving along with the reverse force, thereby reducing the risk.

[0031] Specifically, the cross turntable 41 is connected with a first support rod 42 and a second support rod 43. The first wire winding wheel 44 is slidably connected to the first support rod 42, and the second wire winding wheel 45 is slidably connected to the second support rod 43.

[0032] The cross turntable 41 is provided with a first rod 42 and a second rod 43. Flat positions are provided at the tops of the first rod 42 and the second rod 43 to cooperate with the first wire winding wheel 44 and the second wire winding wheel 45. The purpose of this design is that when the rod moves along the bottom notch direction of the wire winding wheel, there is no relative displacement between the rod and the wire winding wheel. When the rod moves in other directions, it will drive the wire winding wheel to rotate. Moreover, the first rod 42 and the second rod 43 are arranged in a cross shape, so as to ensure that both can act on the two wire winding wheels synchronously, meeting the all-round bending of the front-end execution part.

[0033] Specifically, the holding part 1 at least includes: a grip 11, a trigger 12 and a handle rod 13; the trigger 12 is movably connected to the grip 11, and one end extends into the interior of the grip 11. One end of the handle rod 13 passes through the grip 11 and extends to a position corresponding to the trigger 12 inside the grip 11;

[0034] The other end of the handle rod 13 extends into the connecting part 2 and passes through the second rod 43 extending into the through hole.

[0035] The operator uses the trigger 12 installed on the grip 11 to drive the first steel wire rope 47 to clamp and fix the front end part 3 for the operator, facilitating the operation of the operator.

[0036] Specifically, the front end part 3 includes a front joint 31 and a jaw 32. One end of the front joint 31 is fixedly connected to one end of the connecting part 2. One end of the jaw 32 is fixedly connected to one end of the front joint 31. Moreover, the circumferential outer wall of the front joint 31 is fixedly connected to the second steel wire rope 48 and the third steel wire rope 49.

[0037] There are multiple front joints 31, which drive the jaw 32 to rotate at multiple angles under the action of the second steel wire rope 48 and then the third steel wire rope 49.

[0038] Specifically, an intermediate soft core shaft is installed on one side surface of the jaw 32 and is communicated with the inner wall of the front joint 31 through the intermediate soft core shaft.

[0039] The intermediate soft core shaft is of a hollow type, facilitating the connection between the first steel wire rope 47 and the jaw 32. Then, by operating the trigger 12 to drive the first steel wire rope 47, the jaw 32 can be closed.

[0040] Specifically, the adjusting and rotating assembly 4 includes a first steel wire rope 47. One end of the first steel wire rope 47 is fixedly connected to the trigger 12, and the first steel wire rope 47 passes through the holding part 1, the connecting part 2 and the front joint 31 and is fixedly connected to the jaw 32.

[0041] When the operator holds the trigger 12, the first steel wire rope 47 drives the handle rod 13 to move backward, driving the jaw 32 to move backward, and the notch position of the jaw 32 changes, realizing the closing of the jaw 32.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
