Description

A tracheal hook

technical field

The utility model relates to the technical field of medical surgical instruments, in particular to a trachea hook.

Background technique

Thyroid is a multiple disease, surgery is an effective treatment for thyroid disease, especially thyroid malignant tumor is the fastest-rising tumor, so many patients need surgery. Malignant thyroid tumors need to pull the trachea when cleaning the gas-eating groove or operating on this part, so as to effectively expose the area for surgical operations. At present, pulling is usually done by hand or tracheal retractor. However, the traditional tracheal retractor requires continuous force when used. It is easy to cause upper limb fatigue in a short period of time, causing movement deformation and improper operation, causing the esophagus and other tissues to protrude into the surgical field, increasing the incidence of iatrogenic esophageal and vascular injuries. It is especially serious in muscular patients; in addition, when the ultrasonic knife is used for tumor resection, smoke will be generated, which will affect the surgical field of view and directly affect the effect of the operation.

Utility model content

In order to solve the problems existing in the prior art, the utility model provides a trachea hook, which can relatively fix the position of the trachea hook head in a lateral direction, and can also provide support and assistance, avoiding the continuous fatigue of the operator, and can also Suck away the smoke generated by the ultrasonic scalpel, keep the field of vision clear during the operation, and avoid the ultrasonic scalpel from harming the skin.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

A trachea hook, comprising a handle, one end of the handle is connected to a first pull rod through a first diameter reducing section, and an arc-shaped front plate is connected to an end of the first pull rod far away from the first diameter reducing section, so The bottom end of the front plate is bifurcated and provided with a trachea hook and a support baffle, the trachea hook is arranged on the side of the front plate close to the first pull rod, and a baffle is provided at the front end of the trachea hook, so The support baffle is set on the side of the front plate away from the first pull rod, blunt and smooth protective wings are provided on both sides of the first pull rod and at the connection between the first pull rod and the front plate. The protection wing is facing away from the side of the hook head of the trachea.

One side of the trachea hook head is provided with a number of suction side holes, the handle is connected with an air guide tube, and the end of the air guide tube is connected with a suction tube, the handle, the first reducing section, the first An air guide channel is arranged inside the pull rod, the front plate and the air pipe hook, and the suction side hole communicates with the air guide tube through the air guide channel.

In the above structure, during the operation, soft tissues such as blood vessels, trachea, and esophagus of the patient are put into the trachea hook head and the baffle, and the support baffle is set on the front plate as a support structure, which is placed on the side of the vertebral body during the operation. The medial border of the quadratus and longus colli muscle can not only fix the position of the tracheal hook in a relatively lateral direction, but also provide support and assistance, avoiding the continuous fatigue of the surgeon when retracting the prevertebral structure, and the change of the operative field or the operation When the middle soft tissue breaks into the operation field, the trachea hook head can be moved longitudinally conveniently, which is convenient for the operator. In addition, pressing the suction tube can absorb the smoke generated by the ultrasonic scalpel through the suction side hole, effectively ensuring a clear field of vision when the ultrasonic scalpel removes the lesion, and avoiding skin damage by the ultrasonic scalpel. It is suitable for endoscopic neck incisions and For thyroid surgery without an incision in the neck, it is best to set the suction side hole in the middle of the trachea hook, which is closer to the ultrasonic scalpel and has a better smoke inhalation effect. Blunt and smooth protective wings are set to avoid cutting the surrounding soft tissue during pulling. The end of the handle is connected to the hook head of the trachea through the first reducing section, which can fully expose the surgical field of view and is convenient for the operator to operate.

Preferably, the end of the handle away from the first diameter-reducing section is provided with a second diameter-reducing section, and the second diameter-reducing section is connected with a nerve hook head through a second pull rod. Both sides of the connection between the two pull rods and the nerve hook head are provided with the protective wings.

The two ends of the handle are respectively equipped with tracheal hooks and nerve hooks. When performing thyroid surgery, since two different types of hooks are integrated, there will be no delay in operation time due to confusion between tracheal hooks and nerve hooks. situation, improve the operator's work efficiency.

Preferably, both the tracheal hook head and the nerve hook head are made of titanium alloy. The titanium alloy tracheal hook and nerve hook have a certain degree of toughness, which can prevent irritation or damage to blood vessels and surrounding tissues during the operation.

Preferably, the hook tip of the nerve hook head is blunt. During the operation, the surrounding tissue will not be stabbed, which improves the safety of the operation.

Preferably, the front end of the blocking piece is arc-shaped.

The front end of the blocking piece is arranged in an arc-shaped structure, which can avoid stabbing surrounding tissues during the operation and improve the safety of the operation.
