Description

Half moon board seam tape unit

The technical field is as follows:

the utility model relates to the technical field of orthopedic surgery instruments, concretely relates to meniscus suture belt device.

Background art:

the meniscus is a meniscus-shaped tissue on the tibial articular surface of the knee joint, is composed of fibrocartilage and mainly has the functions of improving the stability of the joint, transmitting load, buffering vibration, lubricating and nourishing the joint. Meniscus injury is mostly caused by external twisting force, and after injury, patients can have symptoms such as joint pain, swelling, and lasso, and if the treatment is not carried out in time, complications such as cartilage degeneration can occur. Meniscus suture is the most ideal operation mode of treatment meniscus damage at present, and the sewing needle has the function of taking the line, before the sewing needle gets into articular cavity, need penetrate the stylolite into the sewing needle, but the sewing needle itself is more tiny, and the stylolite material is softer, and it needs nurse's manual completion to wear the needle, consequently can cause the threading difficulty. And another hollow needle is needed after the suture is finished, the coil is led into the hollow needle, the head end of the suture is led into the coil to be bound, the suture is taken out by pulling out the coil, and the suture is knotted and fixed outside the joint to finish the suture, so that the whole operation process is complicated, the success rate of the threading is low, and the operation progress is influenced. Patent No. ZL201921664097.0 is through setting up hollow suture needle and lead wire ring, hollow suture needle includes the handle, needle bar and needle point, on the needle bar, the fluting is established to the one end that is close to the needle point, the lead wire ring includes first connecting rod, through wires hole and second connecting rod, the both ends in the through wires hole are located to first connecting rod and second connecting rod symmetry respectively, it is at first in the easy threading hole of wearing to penetrate the stylolite with the stylolite, and send into hollow needle bar, outwards pull out the lead wire ring from fluting department and can pass the stylolite with the stylolite, stylolite single line gets into hollow suture needle, make the both ends of stylolite respectively at the both ends of hollow suture needle, avoid the winding of multi-thread at the inside of stylolite, also can avoid the coming off of stylolite in the process of puncturing, reduce operation time and because. However, the suture needle is only suitable for penetrating the suture into the meniscus, after the suture is completed, the head end of the suture still needs to adopt a special tool to penetrate into the meniscus, to hook and pull out for binding and knotting, the operation of hooking and pulling out the head end of the suture is complex, the time consumption is long, and the operation progress is influenced.

The utility model has the following contents:

technical problem to be solved

The utility model aims at providing a meniscus sewing belting for the head end of stylolite is drawn forth in the meniscus sewing operation, solves the operation complicacy that current suturing tool colluded out and pull out the stylolite head end in from the meniscus, and is consuming time longer, influences the problem of operation progress.

The technical scheme is as follows:

in order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a meniscus sewing tape thread device, includes outer tube, interior slide bar and pjncture needle, interior slide bar sets up in the outer tube, the top of interior slide bar is equipped with the press head, be equipped with the bottom plate on the outer tube, the press head with be equipped with compression spring between the bottom plate, compression spring overlaps in the slide bar outside in, the pjncture needle sets up the bottom of outer tube, the bottom of interior slide bar is equipped with elasticity and colludes the claw, elasticity colludes the claw setting and is in the pjncture needle.

The pjncture needle is used for penetrating and aims at the stylolite head end in the meniscus, through pressing the press head with the bottom plate can with compression spring compression, interior slide bar is in slide in the outer tube, elasticity colludes the claw and is in when compression spring is compressed, follow stretch out in the pjncture needle, open through self elasticity will elasticity colludes the claw and aims at the stylolite head end, loosens the press head, interior slide bar is in slide under compression spring's the restoring force, elasticity colludes the claw and presss from both sides tight stylolite head end and is withdrawed extremely in the pjncture needle, the stylolite head end quilt elasticity colludes the claw and colludes, can follow the extraction of pjncture needle is worn out externally, is convenient for tie a knot fixedly, through elasticity colludes the claw and catches on the easy operation convenience of pressing from both sides tight styl.

Furthermore, the outer sleeve is a flexible metal mesh tube, the inner sliding rod is divided into two sections, the upper section is a hard straight rod, and the lower section is a flexible rod, so that the direction of the puncture needle can be conveniently adjusted in the puncture process, and the puncture needle can be conveniently aligned to the head end of the suture thread.

Furthermore, the elastic hook claw is composed of two or four arc-shaped metal sheets which are symmetrically arranged relative to the axis of the inner sliding rod, the arc-shaped metal sheets are made of memory alloy or stainless steel materials, and the arc-shaped metal sheets can keep elasticity and can conveniently extend out of and retract into the puncture needle, so that clamping stagnation is avoided.

(III) the beneficial effects are as follows:

compared with the prior art, the utility model discloses the beneficial effect who produces is: through slide bar in the interior setting of outer tube, the bottom of outer tube sets up the pjncture needle, and the bottom of interior slide bar sets up elasticity and colludes the claw, and elasticity colludes the claw and can promote compression spring control it through the operation and stretch out and withdraw from the pjncture needle, can be convenient when meniscus suture operation catch on the head end of stylolite and pull out and knot fixedly, reduces the complexity of operation, effectively improves operation efficiency.
