Embodiment 1

[0051] see figure 1 with figure 2 As shown, this embodiment provides a neck bending structure of an endoscopic surgical instrument, including: a snake unit and a traction unit suitable for pulling the snake unit to bend; the snake unit includes several sequentially hinged Snake bone joint 100 : the snake bone joint 100 includes a base 101 and a pair of wings 102 integrally provided on both sides of the base 101 , the base 101 and the wings 102 are integrally formed.

[0052] see Figure 7 As shown, the base 101 has a protrusion 103 protruding from a pair of wings 102, and the part of the base 101 between the pair of wings 102 is concavely provided with a base 101 suitable for another snake bone joint 100. The protrusions 103 are hingedly connected to the recesses 104 ; the recesses 104 and the protrusions 103 are coaxially distributed.

[0053] Optionally, the cross-sections of the protrusions 103 and the depressions 104 are arc-shaped structures. In order to improve the s...

Embodiment 2

[0066] see figure 1 As shown, on the basis of the neck bending structure of the endoscopic surgical instrument in embodiment 1, this embodiment provides an endoscopic surgical instrument, including: A handle unit 1, a connecting pipe unit 2, a neck unit 3 and a head unit 4 are provided in sequence. The handle unit 1 includes an upper cover body and a lower cover body 302 adapted to be closed and connected, and a receiving cavity 303 is formed between the upper cover body and the lower cover body 302 .

[0067] see image 3 As shown, the neck unit 3 adopts the neck bending structure of Embodiment 1; the bases 101 of several snake bone joints 100 of the snake bone unit of the neck bending mechanism penetrate a through hole 110, and the through hole 110 is located at the bottom of the base 101. center line. In order to facilitate the neck bending structure of this embodiment to be connected to the head unit 4 and the connecting pipe unit 2 respectively, the snake bone unit of ...

Abstract

The invention discloses an endoscope surgery instrument and a neck bending structure thereof. The endoscope surgery instrument comprises a snake bone unit and a traction unit, the traction unit is suitable for bending of the snake bone unit, the snake bone unit comprises a plurality of snake bone joints which are sequentially hinged, each snake bone joint comprises a base portion and a pair of wing portions, the wing portions are integrally arranged on two side of the corresponding base portion, each base portion is provided with a projection portion and a recessed portion, each projection portion projects a pair of wing portions, each recessed portion is arranged at the portion of the corresponding base portion positioned between a pair of wing portions in a recessed manner and is suitable for hinging of a projection portion of a base portion of the other snake bone joint, the recessed portions and the projection portions are coaxially distributed, the traction unit comprises a pair of traction holes, a pair of pull wires and a traction component, the traction holes penetrate a pair of wing portions of a plurality of snake bone joints along the direction of the corresponding baseportion, the pull wires in a pair of traction holes are suitable for penetrating of a plurality of snake bone joints, and the traction component is suitable for traction of a pair of pull wires.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to an endoscopic surgical instrument and its neck bending structure. Background technique [0002] In some endoscopic operations, especially the surgical instruments that enter the human body through the endoscopic channel or the natural channel of the human body, the tissue is stripped, cleaned, milled and resected by controlling the instrument head forceps (or other functional heads) through the handle When the instrument is limited by the diameter of the channel, the shaking range is limited, and the arrival position of the head (surgical area) is relatively narrow. Enlarging the channel does not match the "small channel, large-scale surgical purpose" of endoscopic surgery. In order to overcome the above-mentioned problems, there have been surgical instruments with necks that can be pre-bent. Using the inherent elasticity of the neck metal of the surgical instrument, the angle i...
