The utility model discloses a sharp-pointed end is set to the supporting part end of drag hook so that pierce the skin, and the supporting part is whole to be set to the spiral so that can get into subcutaneous space with the rotation, but height-adjusting's support in the operation can be connected to the operation portion that sets up at the other end of drag hook, upwards carry to draw fixed back to continue to suspend in midair and pull operation position skin, reach and obtain stable thyroid endoscope operation space's purpose exempting from to aerify or reduce under the gas filled condition.
Description
Technical Field
The utility model relates to a medical instrument, more specifically say, relate to a thyroid cavity mirror operation drag hook.
Background
The operation space establishment and the operative field exposure of the thyroscopic surgery are important steps. Anatomically, the thyroid is located in the potential lumen behind the anterior cervical muscle group, on both sides of the trachea, and in front of the carotid sheath. The first step of the operation is to expand the potential cavity into a real cavity, carbon dioxide gas is injected at a continuous high flow rate after the puncture outfit is arranged through a tunnel dilator in the conventional method, the pressure is maintained at 6-8mmHg, after the tendon and the membrane gap below the platysma cervicis is dissociated, the anterior cervical muscle group is retracted through a skin puncture drag hook or a transdermal suspension wire, and the thyroid tissue is exposed.
Continuous infusion of carbon dioxide may cause hypercapnia, and continuous pressure may also cause subcutaneous emphysema, even with severe complications such as air embolism when venous blood vessels are damaged. The method of adopting many transdermal hanging wires to carry out skin and suspend in midair and increase the damage of neck skin, and suspend the dynamics inadequately, hardly reach stable support, can cause instantaneous carbon dioxide pressure to reduce when needing aspirator suction aerial fog or oozing blood exudate in the art, cause the space to collapse, influence art field and operation. The method of using a plurality of kirschner wires to penetrate the skin in parallel for suspension also can form a plurality of puncture holes, increase the damage of the skin and subcutaneous tissues, increase the risk of accidental injury operators and assistants due to the exposed puncture tip, and make the external fixing device more complicated.
CN104013445A discloses an chamber mirror thyroid surgery drag hook, including the supporter that both ends were equipped with the muscle fixed head, the supporter is rectangular form elastic support strip, and the elastic support strip both ends are connected through the ball pivot the muscle fixed head forms certain space in order to place the chamber mirror subcutaneously through two supporters, nevertheless the structure is more complicated, only can play the function of traction muscle, can not realize the support to chamber mirror operating space. CN2745517Y discloses a V-shaped cavity mirror thyroid surgery retractor, which only has the function of retracting the muscle in front of the neck to expose the thyroid and does not help to support the surgery space.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in, to prior art's above-mentioned defect, provide a thyroid cavity mirror operation drag hook, can obtain stable thyroid cavity mirror operation space.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a thyroid cavity mirror surgery retractor, includes operation portion, supporting part and connects the connecting rod of operation portion and supporting part, the supporting part has the at least round spiral coil that is located the plane perpendicular with the extending direction of connecting rod, the inner of spiral coil is connected with the one end of connecting rod, the outer end of spiral coil forms most advanced.
According to the utility model discloses an embodiment, the pointed end is in the coplanar or is the plane of keeping away from the spiral coil at an angle with the spiral coil.
According to an embodiment of the invention, the tip is at an angle of 150 ° to the plane of the helical coil.
According to an embodiment of the invention, the tip is 3mm long.
According to the utility model discloses an embodiment, the operating portion is for connecting in the couple or the link of the connecting rod other end.
According to the utility model discloses an embodiment, operation portion, supporting part and connecting rod are whole to be made by the metal strip.
Implement the utility model discloses a thyroid cavity mirror surgery drag hook has following beneficial effect: the utility model discloses a sharp-pointed end is set to the supporting part end of drag hook so that pierce the skin, and the supporting part is whole to be set to the spiral so that can get into subcutaneous space with the rotation, but height-adjusting's support in the operation can be connected to the operation portion that sets up at the other end of drag hook, upwards carry to draw fixed back to continue to suspend in midair and pull operation position skin, reach and obtain stable thyroid endoscope operation space's purpose exempting from to aerify or reduce under the gas filled condition.
Drawings
The invention will be further explained with reference to the drawings and examples, wherein:
fig. 1 is a schematic structural view of the thyroid endoscopic surgery retractor according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the thyroid endoscopic surgery retractor 100 according to an embodiment of the present invention is mainly composed of a supporting portion 10 for supporting the skin, an operating portion 30 mounted to a surgical stent, and a connecting rod 20 connecting the supporting portion 10 and the operating portion 30, wherein the supporting portion 10 and the operating portion 20 are respectively connected to both ends of the connecting rod 20. As shown in fig. 1, the support 10 includes a spiral coil 11, an inner end of the spiral coil 11 is connected to an end of the connecting rod 20, and an outer end of the spiral coil 11 forms a sharp tip 12 to facilitate skin penetration. The number of turns of the spiral coil 11 is equal to or greater than one, the spiral plane of the spiral coil 11 is located in a plane perpendicular to the extending direction of the connecting rod 20, and the diameter of the turns can be set to be different sizes according to different application positions of the retractor 100. The spiral plane support part 10 can conveniently rotate to enter the human body and can stably support the skin. The tip 12 may be in the same plane as the helical coil 11 or angled away from the plane of the helical coil 11. The tip 12 may be shaped in a variety of sharp shapes, preferably 3mm long, and is positioned at an angle of 150 ° to the plane of the helical coil 11 to avoid subcutaneous tissue damage caused by displacement or rotation during traction. The operation part 30 is connected to the other end of the connecting rod 20, is in a hook shape (in different embodiments, other shapes such as a pull ring shape can be provided), is used for connecting a height-adjustable bracket in an operation, and continuously suspends and pulls the skin of an operation part after being lifted upwards and fixed, so that the purpose of obtaining a stable thyroscopic operation space under the condition of no inflation or reduced inflation is achieved.
The above-mentioned thyroid endoscopic surgery retractor 100 of the present invention can be made of a metal strip with a certain hardness, and the diameter of the metal strip can be set to different sizes. The retractor 100 may be made of other materials with certain strength according to various embodiments of the present invention.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
