Description

Tumor tractor

Technical Field

The utility model belongs to the technical field of medical instrument, a tumour tractor is related to.

Background

In the operation of tumor resection, the key to the smooth and complete tumor resection is the tumor exposure and separation. In the prior art, the tumor retractor is directly used for clamping a tumor envelope and further moving to separate the tumor from surrounding normal tissues so as to gradually cut the tumor, and the tumor body is prevented from being damaged and completely cut off in the cutting process.

The existing tumor retractor comprises two clamping rods which are arranged in a crossed mode, during operation, a doctor holds the extirpation forceps by a hand, and different acting forces are applied to the clamping rods by the hand to clamp tumors with different sizes.

Because the texture of tumor tissue is thin and soft, when leading to current centre gripping tumour, if the clamping-force is too little, lead to the difficult centre gripping of tumour, if the clamping-force is too big, easily press from both sides the tumour and break, the flesh of blood is fuzzy, leads to the operation field of vision unclear, and then leads to the tumour to clear away not thoroughly or tumour and pollutes.

Disclosure of Invention

The utility model aims at providing a tumor retractor aiming at the above problems existing in the prior art, solving the problem that the tumor body is damaged easily in the operation of tumor clamping.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a tumor retractor, includes the centre gripping arm, articulated on the centre gripping arm have at least three clamping jaw, a serial communication port, wear to be equipped with the push rod that can follow centre gripping arm length direction and remove on the centre gripping arm, the one end of push rod stretches out the centre gripping arm and is located between the above-mentioned clamping jaw, every the clamping jaw all links to each other with the push rod, and the clamping jaw opens or is closed when the length direction of push rod along the centre gripping arm removes, the one end that the centre gripping arm was stretched out to the push rod is equipped with the light.

The clamping jaw is hinged to the clamping arm and connected with the push rod, and when the push rod moves downwards along the length direction of the clamping arm, the clamping jaw is opened; when the push rod moves upwards along the length direction of the clamping arm, the clamping jaws are closed, and therefore the tumor is clamped. Locate the push rod between the clamping jaw, and set up the light in the one end that stretches out the centre gripping arm, when to the tumour centre gripping, the relative centre gripping arm of light is more close to the tumour, and light removes along with the clamping jaw, and the accurate position of finding the tumour of the doctor of being convenient for, and the rethread clamping jaw carries out the centre gripping to the tumour, and the centre gripping in-process, light is closely gathered on the tumour, and the doctor of being convenient for looks directly at tumour and operation wild, avoids taking place the tumour body damage in the tumour centre gripping operation. If the clamping is not in place, the clamping position can be timely adjusted, so that the side damage to normal tissues around the tumor is avoided, and the clamping precision of the tumor is improved. Wherein, the quantity of clamping jaw can be a plurality of, drives a plurality of clamping jaws simultaneously by the centre gripping arm and carries out the centre gripping, increases the area of contact of clamping jaw and tumour on the one hand, makes clamping-force evenly act on the tumour, and avoids the tumour of having been held to deviate from the clamping jaw, and on the other hand improves the precision of centre gripping, avoids repeated centre gripping, further avoids taking place the tumour body damaged in the tumour centre gripping operation.

In the tumor retractor, the clamping jaws are arranged along the circumferential direction of the push rod, and the illuminating lamp is fixed on the end face of the push rod.

The setting position of light is convenient for light irradiation on the tumor body, and light removes along with the clamping jaw, and the doctor of being convenient for looks directly at the boundary and the operation field of tumor and surrounding tissue, improves the centre gripping precision, avoids taking place the tumor body damaged in the tumor centre gripping operation.

In the tumor retractor, the follower rod is arranged between the push rod and the clamping jaw, one end of the follower rod is hinged with the clamping jaw, and the other end of the follower rod is hinged with the push rod. The structure enables the follower lever to conveniently drive the clamping jaws to open and close through the push rod.

In foretell tumour tractor, tumour tractor still is including the main part of connecting the centre gripping arm, be equipped with the reel on the centre gripping arm, the winding has the pull wire on the reel, the pull wire links firmly with the push rod. By rotating the reel, the traction wire is wound or unwound, thereby driving the push rod to move along the length direction of the clamping arm.

In the tumor retractor, the clamping arm is internally provided with a sliding groove which is arranged along the length direction of the clamping arm, the push rod is provided with a sliding block which is embedded into the sliding groove and can move along the sliding groove, and the sliding block is hinged with the follower rod. When the push rod moves, the sliding block moves along the sliding groove, so that the sliding block moves along the length direction of the clamping arm, and the push rod is prevented from shaking in the moving process.

In the tumor retractor, the clamping arm is provided with a spherical head part, the main body is provided with a spherical cavity, the spherical head part is embedded into the spherical cavity, the main body is provided with a bolt in a penetrating way, and the rod part of the bolt can be abutted against the spherical head part. This structure makes the relative main part of centre gripping arm ability rotate, and the push rod can rotate relative main part promptly, realizes the angle modulation of the clamping jaw of clamping jaw to the clamping jaw carries out the centre gripping according to the growth position of tumour to the tumour, improves the centre gripping precision and the operation simple operation nature of clamping jaw from this.

In the tumor retractor, the clamping jaw is provided with a sucking disc. The sucking disc can communicate the negative pressure, and after the clamping jaw is close to the tumour, adsorb the tumour by the sucking disc.

In the tumor retractor, the tumor retractor further comprises a hose communicated with the suction disc, the main body is provided with a ventilation channel, and the hose is fixedly connected with the main body and is communicated with the ventilation channel. The structure leads the retractor to have compact structure and integrated functions, and is convenient for doctors to operate.

Compared with the prior art, the utility model provides a pair of tumor retractor has following advantage:

1. during the operation, because the clamping jaw directly reaches the tumor body, and the light that is located between the clamping jaw can penetrate the operation field directly, and light removes along with the clamping jaw, makes clear the demarcation of seeing tumor and normal tissue of doctor, dissects the separation, improves doctor's centre gripping precision from this.

2. The follower rod drives the clamping jaws to open and close simultaneously, so that the clamping jaws are stressed uniformly on one hand, and the clamping stability is improved on the other hand.

3. The tumor is adsorbed by the sucker in a uniform force manner, so that the tumor is prevented from being physically damaged and broken when the tumor is pulled by the clamping jaw.
