Description

Instrument capable of hooking and pushing for arthroscope

Technical Field

The utility model belongs to the field of medical operation auxiliary instrument, concretely relates to arthroscope is with can colluding line can push away knot apparatus.

Background

In the current aspect of rotator cuff tear treatment, arthroscopes are widely used as treatment aids. An arthroscope is a rod-like optical instrument with a diameter of about 5mm for observing the internal structure of a joint, and is an endoscope used by doctors for diagnosing and treating joint diseases. The technical operation under the arthroscope is beneficial to promoting the healing of rotator cuff tendon and bone surface. Firstly, specific types (crescent, L, U or composite) of rotator cuff tear are determined, then a holding forceps is used for grabbing and pulling the rotator cuff tear edge, and the texture and the mobility of the rotator cuff stump are explored and evaluated. If the bone is crescent-shaped, the bone bed is easier to be directly sutured by an anchor; if the L-shaped tear is formed, firmly sewing the torn horizontal section with an anchor and fixing the horizontal section at a dead point, and then sewing the longitudinal section edge to edge; in the case of U-shaped or composite tears, the degree of these tears is usually greater and it is necessary to convert the tear into a crescent tear with a smaller tear area and lower edge tension by edge-to-edge stitching and then to fasten it to the stop. Common methods for suturing and fixing the rotator cuff tear under the arthroscope mainly comprise single-row suturing, double-row suturing and a suturing bridge technology. Wherein, the double-row suture can increase the contact area of the tendon and the bone bed compared with the single-row suture, but the clinical curative effect has no significant difference; the suture bridge technology can recover the anatomical structure and the biomechanical strength of the rotator cuff to the maximum extent, and the postoperative curative effect is effectively improved. However, in any method, suturing requires withdrawing the suture and tying it. However, when knotting, the knotted knots are generally pushed and knotted by using surgical forceps, and particularly, when knotting, the knots are often slipped and dropped or are not pushed and knotted in place, so that the knots are not firm, and the surgical suture is not ideal. Therefore, it is necessary to design an apparatus that can easily hook out a suture and simultaneously push the knot end of the suture.

SUMMERY OF THE UTILITY MODEL

For overcoming the problem among the prior art, the utility model provides an arthroscope is with can colluding line can push away knot apparatus, including a person font handle, pivot department of handle connects a knot pole that pushes away forward, the front end that pushes away the knot pole sets up colludes the pincers, the head that colludes the pincers openly sets up a knot hole that pushes away.

In the wire-hooking and knot-pushing instrument for the arthroscope, a connecting rod is arranged in the knot-pushing rod, one end of the connecting rod is connected with the handle, and the other end of the connecting rod is connected with the wire-hooking pliers; the switch of the head part of the wire hooking clamp is controlled to be closed through the connecting rod.

The utility model provides an among the arthroscope can collude the line and can push away knot apparatus, the diameter that pushes away knot hole is 6mm ~ 8 mm.

The utility model provides an among the arthroscope can collude line can knot pushing device, the diameter of colluding the line pincers is greater than the diameter of knot pushing rod.

The utility model provides an arthroscope is with can colluding the line can push away in the knot apparatus, push away the axial lead in knot hole with the axial lead that pushes away the knot pole is located same straight line.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses on the basis of colluding the line pincers, openly push away the knot hole through increasing one at the head, can easily collude the stylolite, can impel the knot that the stylolite was knotted again for the completion of supplementary operation.

Detailed Description

The present invention is described in greater detail below with reference to the drawings, in which preferred embodiments of the present invention are shown, and it is to be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

As shown in fig. 1 to 4, the utility model provides a joint mirror is with can colluding line can push away knot apparatus, including a herringbone handle 1, a knot pole 2 that pushes away is connected forward in the pivot department of handle 1, the front end of knot pole 2 that pushes away sets up colludes pincers 3, the head of colluding pincers 3 openly sets up a knot hole 4 that pushes away. A connecting rod is arranged in the push rod 2, one end of the connecting rod is connected with the handle 1, and the other end of the connecting rod is connected with the wire hooking clamp 3; the switch of the head of the wire hooking clamp 3 is controlled to be closed through the connecting rod. The diameter of the knot pushing hole 4 is 6 mm-8 mm, preferably 6mm, 7mm or 8 mm.

Referring specifically to fig. 3 and 4, the diameter of the wire clipper 3 is larger than that of the knotting bar 2. The axial lead of the knot pushing hole 4 and the axial lead of the knot pushing rod 2 are positioned on the same straight line.

During operation, the handle is opened and closed, the switch of the head of the thread hooking clamp is controlled to be closed through the connecting rod, the handle is operated under the monitoring of an arthroscope, the suture thread is hooked by the head of the thread hooking clamp in a joint cavity, the suture thread is pulled out and knotted, after knotting is completed, the suture thread is clamped into the knot pushing hole, then the free end of the suture thread is pulled by one hand, the handle is held by the other hand, and the untightened knot can be pushed forwards and tightened under the extrusion effect of the head of the thread hooking clamp.
