Abstract
The utility model discloses a thyroid dissector used for endoscopic thyroid operation, the structure of which as follows: dissector is rod-shaped, the front-end is blunt body, the root part of blunt body has ring groove, and the back-end is fixed on and connected with the handle. When you using this device, wrapping the front-end of dissector with sterile gauze, then to tied the gauze tightly with yarn and fixing the dissector on the ring groove; Putting the front-end of dissector into surgery space through operation hole, the sterile gauze at the front-end of dissector should close the surface of gland, dissecting gently the surface tissues of gland at the different direction follow the natural arc of gland. This will expose completely the thyroid gland, nervous and the upper, middle and lower blood vessels, the bleeding caused by vascular injury in the course of separation can be avoided.
Description
Technical field
This utility model relates to medical apparatus and instruments, especially the thyroid dissector of device for endoscopic thyroid surgery special use.
Background technology
Thyroid disease is a kind of commonly encountered diseases, frequently-occurring disease, especially is mainly in young women, and operative treatment is one of final healing means of this disease, also is the most frequently used, the most effective means.The tradition open surgery need be left over an operative scar that is about 6～8cm at cervical region, stays dense psychological shade to the patient, has a strong impact on their daily life study and work.Device for endoscopic thyroid surgery thoroughly changes this situation, in cure diseases, makes wound small hidden, has taken into account the advantage of safe thyroidectomize pathological changes and beauty treatment, obtains carrying out more and more widely at present.In the device for endoscopic thyroid surgery, separating the manifest thyroid body of gland is key operation, and peeling off of thyroid success appears, and the art open country that can guarantee to perform the operation is clear, avoids intraoperative hemorrhage and damages important nerve.
In the existing device for endoscopic thyroid surgery, carry out thyroid separation and appear main application plastic suction tube and carry out.Suction catheter is a plastic, and quality is harder, and is in light weight, nonelastic and plasticity, and front end is sharp keen, thereby operation inconvenience, and blood vessel and other tissue of damage vicinity easily.
The patent No. is that the utility model of CN200420098941.5 discloses a kind of drag hook that is used for thyroid operation under the mirror of chamber, this device for endoscopic thyroid surgery drag hook is that tinsel forms through bending process, the drag hook body of drag hook is " V " font at a wide end, one end is a needle point, the other end continues mutually with the drag hook bar, and the drag hook bar joins with the drag hook handle again.During use, thrust skin, enter the thyroid intracavity, under the assistance of chamber mirror apparatus, the muscle group in throat is pulled to the outside, thyroid is fully exposed, the operation that is beneficial to perform the operation through the rotation drag hook by the needle point of external preparation for skin drag hook.But this drag hook complex structure, and the one end is needle point in the operation process as can damage contiguous blood vessel or other tissue accidentally, brings certain risk to operation.
The utility model content
The purpose of this utility model provides the thyroid dissector that a kind of device for endoscopic thyroid surgery is used, and thyroid is successfully peeled off appeared, and guarantees that operation art open country is clear, avoids intraoperative hemorrhage and damages important nerve.
For reaching above-mentioned purpose, the thyroid dissector structure that device for endoscopic thyroid surgery of the present utility model is used is as follows: the detacher body is shaft-like, and front end is a blunt body, and the root of blunt body has annular groove, and rear end and handle are fixedly connected.
For the ease of processing, described blunt body is spherosome or spheroid.
For the ease of antiseptic gauze being fixed on the detacher front end, the width of described annular groove is advisable with 5～10mm.
Manipulate for the ease of the patient, described detacher body can be made up of bending obtuse-angulate leading portion and back segment, and the angle of bending is advisable with 120 °～160 °, and the length of leading portion is 300～400mm, the length of back segment and handle and be 90～110mm.
Be easy in order to manipulate grasp control, described detacher body is made by rustless steel.
Thyroid dissector of the present utility model is to use like this: sterile gauze is wrapped in the detacher front end, fastens on annular groove with yarn; The detacher front end is passed through in the handle hole implantation surgery space, the sterile gauze of detacher front end is close to gland surface, carry out variant direction along body of gland nature radian and gently peel off the gland surface tissue, get final product complete manifest thyroid body of gland and upper, middle and lower utmost point blood vessel, nerve.
Thyroid dissector of the present utility model changes the shortcoming that traditional operation detacher short handle can not be applied to endoscope-assistant surgery, with the long handle design, can arrive at thyroid in device for endoscopic thyroid surgery and put than deep-seated.Front end is blunt spheroid, can injured blood vessel during use; The design of the annular groove of blunt spheroid root can be fastened sterile gauze securely and can come off in the above and not and produce displacement.Front end wraps up with sterile gauze, and flexible and plasticity is close to the body of gland operation, avoids damage important blood vessels nerve on every side, reduces and peels off the complication that causes nerve injury; And the quality softness avoids injured blood vessel to cause bleeding in the separation process.Detacher is bent into certain angle for forward and backward two sections, is convenient to the patient and manipulates.The design of stainless steel metal rod increases apparatus weight, and good hand touch is grasped control easily.This utility model is simple in structure, and is easy to manufacture.
Utility model people's successful Application thyroid dissector of the present utility model carries out nearly 400 examples of device for endoscopic thyroid surgery, hemorrhage 0～10ml, and average out to 2.4ml, hoarseness appears in none example of postoperative, drinking-water is choked and recurrent nerve injury complication on the larynx such as coughed.
Description of drawings
Fig. 1 is the structural representation of thyroid dissector of the present utility model.
The specific embodiment
As shown in Figure 1, thyroid dissector of the present utility model is formed by fixedly connecting by detacher body 1 and handle 2, and detacher body 1 is made by rustless steel, and handle 2 is made of plastics.The front end of detacher body 1 is a blunt body 3, and the root of blunt body 3 has annular groove 4.Blunt body 3 can be to be spherosome or spheroid or other shape of the sharp keen corner of tool not.For the ease of operation technique, detacher body 1 is by leading portion and back segment is bent forms, and angulation A is 120 °～160 °.The length a of leading portion is about 300～400mm, and the length of back segment and handle and b are 90～110mm.
During use, the sterile gauze (not shown) is wrapped in outside the blunt body 3, and sterile gauze is fastened on annular groove 4, sterile gauze can not come off, also can not move on to detacher body rear end with yarn.The width of annular groove is that 5～10mm is more suitable.
During operation, the patient holds handle, the detacher front end is passed through in the handle hole implantation surgery space, the sterile gauze of detacher front end is close to gland surface, carry out variant direction along body of gland nature radian and gently peel off the gland surface tissue, get final product complete manifest thyroid body of gland and upper, middle and lower utmost point blood vessel, nerve.
