Description

Endoscope thyroid surgery retractor

Technical Field

The utility model belongs to the technical field of medical treatment auxiliary articles for use, especially, relate to an chamber mirror thyroid surgery drag hook.

Background

Currently, the current state of the art commonly used in the industry is such that:

the incidence and detection rate of thyroid nodules, including thyroid cancer, has risen year by year. Surgery is a major and fundamental treatment of thyroid nodules, including thyroid cancer. Traditional open surgery can leave permanent scar in the neck of a patient, and has obvious negative effects on social life and psychological state of the patient. Thyroid surgery based on endoscopic technology has been widely performed at home and abroad for nearly 10 years. The endoscopic thyroid surgery can effectively reduce and avoid the wound on the neck, improves the aesthetic effect of the surgery, has unique aesthetic advantages, and becomes the priority of partial patients. With the progress of technology and instruments, endoscopic thyroid surgery must take an increasingly important position in thyroid surgery.

The lack of natural lacunae in endoscopic thyroid surgery makes the exposure of the thyroid gland sufficiently and effectively more important, because the space is relatively narrow. Good intraoperative exposure is the basic condition of endoscopic thyroid surgery, and only then, the basis of ensuring the safety of the surgery, improving the surgery quality and effectively protecting the functions can be realized. At present, most of endoscope thyroid retractor commonly used in clinic is made of metal wires, and the retractor is soft in texture, easy to deform and poor in drawing effect. Also, its relatively sharp tip can cause tissue side damage, increasing the risk of surgery. In addition, the existing combined endoscope thyroid gland retractor is inconvenient to clamp and the hook type of the retractor is not favorable for convenient operation in the operation. Moreover, the current endoscopic thyroid retractor is mostly made of metal materials, and is not operated properly in the operation, so that the energy apparatus is damaged.

In summary, the problems of the prior art are as follows:

most of endoscope thyroid retractor commonly used in clinic is made of metal wires, and the retractor is soft in texture, easy to change and poor in drawing effect. Also, its relatively sharp tip can cause tissue side damage, increasing the risk of surgery. In addition, the existing combined endoscope thyroid gland retractor is inconvenient to clamp and the hook type of the retractor is not favorable for convenient operation in the operation. Moreover, the current endoscopic thyroid retractor is mostly made of metal materials, and is not operated properly in the operation, so that the energy apparatus is damaged.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides an improved endoscope thyroid surgery retractor.

The utility model discloses a realize like this, a chamber mirror thyroid surgery drag hook is provided with:

pulling a hook;

a sleeve is poured at the upper end of the drag hook, the sleeve is connected with a connecting rod through threads, and a handle is welded at the right end of the connecting rod;

the needle channel expander is provided with a handle, the left end of the handle is welded with a connecting rod, and the left end of the connecting rod is cast with a needle head.

The utility model discloses a sleeve can make things convenient for centre gripping and fixed in the art to do benefit to the direction adjustment of drag hook in the art. The configuration of the draw hook is optimized, the sleeve end of the draw hook is designed to be V-shaped, the direction adjustment of the draw hook is further facilitated, and the influence of the draw hook on the operation visual field is reduced. The length of the basic type of the drag hook is set to be 2.5cm according to the requirement of a conventional operation, so that the suprathyroid pole and VI area lymph node tissues can be fully exposed by a single drag hook.

The lower end of the drag hook is provided with an elbow bent inwards, so that reliable traction is guaranteed, tissues are not easy to slip, and the tip is designed into an arc shape, so that the tissues are prevented from being damaged secondarily. In addition, the surface of the retractor is coated with an insulating layer, so that the energy instrument is prevented from being damaged in the operation.

Furthermore, a conical head is poured at the joint of the handle and the connecting rod.

The utility model discloses a cone head can increase the engineering intensity of drag hook, strengthens its durability.

The utility model discloses an advantage does with positive effect:

the utility model discloses the drag hook can effectively carry out the tissue tractive in chamber mirror thyroid surgery, establishes good operation field of vision, guarantees the security of operation and the quality of operation, and the effectual function protection that carries on realizes the unity of chamber mirror thyroid surgery quality and aesthetic requirement. Through the telescopic design of drag hook, make things convenient for the centre gripping of drag hook and fixed. The optimization of the draw hook configuration is beneficial to the adjustment of the draw hook direction in the operation, reduces the risk of side damage to tissues and further improves the safety of the operation. The elbow can effectively avoid tissue slippage, and ensure convenient and reliable traction. The unique insulation is involved, and potential damage to the energy instrument can be effectively avoided.

The draw hook is made of hard materials, does not have deformability, and can effectively guarantee the drawing effect. The drag hook is combined, and different parts are connected through threads and the like, so that the drag hook is favorable for assembly in vivo and convenient to operate. The configuration of the draw hook is optimized, and the risk of tissue side injury is reduced on the basis of full exposure. On the basis of the basic model, the serialization of the model and the shape is formed, so that the surgical instrument is suitable for different surgical operation requirements. In addition, the material of the drag hook is further optimized, so that the drag hook is not insulated, and the damage of the energy instrument caused by accidental contact with the energy instrument is avoided.
