There is a triangular space in the middle of the double-arc triangular cone. There is a nut in the middle of the bracket. The upper end is connected to the handle, and the lower end is connected to the herringbone connecting rod. The herringbone connecting rod is located in the triangular space between the two spreading arms. The lower ends of the herringbone connecting rod are respectively connected to the two spreading arms through hinge shafts. The tip of the lower end of the arm is covered with a plastic sleeve or a rubber sleeve.

Description

tooth extender

technical field

The invention relates to the technical field of medical instruments, in particular to a tooth expander.

Background technique

For some patients with sudden symptoms, such as epilepsy patients, cerebral hemorrhage patients, drowning people, etc., the teeth are tightly closed during rescue, and it is difficult for medical staff to feed the medicine from the mouth or take out foreign objects in the mouth. At this time, a medical treatment is needed. The device quickly and safely props up the patient's tightly closed teeth. At present, there is no good way to solve the above-mentioned problems.

Contents of the invention

The technical task of the present invention is to solve the deficiencies of the prior art and provide a tooth spreader.

The technical solution of the present invention is realized in the following manner, and its structure is composed of a handle, a screw, a bracket, a spreader arm and a herringbone connecting rod, wherein the support is semi-elliptical, and the two ends are connected to the upper end of the spreader arm through a hinge , the stretching arms form a curved cone with a groove-shaped section, and the two stretching arms are arranged opposite to each other to form a double-arc triangular cone. There is a triangular space in the middle of the double-arc triangular cone, and a nut is arranged in the middle of the bracket. The upper end of the screw rod is connected with the handle, and the lower end is connected with a herringbone connecting rod. The herringbone connecting rod is located in the triangular space between the two spreading arms. The tip of the lower end of the spreading arm is covered with a plastic sleeve or a rubber sleeve.

The method of use is as follows:

Insert the lower tips of the two spreading arms between the upper and lower teeth of the patient, turn the handle to drive the screw to rotate, the screw and the nut thread in the middle of the bracket drive the upper end of the herringbone connecting rod to move down, and the lower end of the herringbone connecting rod will move the spreading arm to the When the spreader is opened, it also spreads the patient's teeth, so that the medical staff can carry out oral examination and rescue. The upward pulling action of the herringbone connecting rod is folded and merged for the next use.

A tooth spreader of the present invention has the following outstanding beneficial effects: it is simple in structure, easy to operate, can greatly reduce the labor intensity of the operator, does not damage the patient's teeth, and can quickly open the mouth, which is safe and convenient. practical.

Description of drawings

Accompanying drawing 1 is the structural representation of tooth spreader;

The marks in the accompanying drawings represent respectively: handle 1, screw rod 2, support 3, hinge 4, herringbone connecting rod 5, twisted shaft 6, stretching arm 7, triangular space 8, plastic sleeve cover 9, nut 10.

Detailed ways

The tooth expander of the present invention will be described in further detail below in conjunction with the accompanying drawings.

A tooth spreader of the present invention is composed of a handle 1, a screw rod 2, a bracket 3, a spreader arm 7 and a herringbone connecting rod 5, wherein the bracket 3 is semi-elliptical, and the two ends are connected by hinges and braces. The upper ends of the opening arms 7 are connected, and the opening arms 7 are in the shape of a curved cone with a groove-like cross section. The two opening arms 7 are arranged opposite to each other to form a double-arc triangular cone. There is a triangular space 8 in the middle of the double-arc triangular cone. There is a nut 10, the screw rod 2 is connected with the nut 10 through threads, the upper end of the screw rod 2 is connected to the handle 1, and the lower end is connected to the herringbone connecting rod 5, which is located in the triangular space 8 between the two spread arms 7, the herringbone The lower end of glyph connecting rod 5 is connected with two stretching arms 7 by hinge shaft 6 respectively, and the lower end tip of two stretching arms 7 is covered with plastic sleeve 9 or rubber bushing.

Example

The tooth spreader of the present invention is very simple and convenient to manufacture, and the handle, bracket, herringbone connecting rod and spreader arm are made of stainless steel plate through stamping and forming process.

The method of use is as follows:

Insert the lower tips of the two stretching arms between the upper and lower teeth of the patient, turn the handle to drive the screw to rotate, and the nut in the middle of the screw and the bracket will drive the upper end of the herringbone connecting rod to move down, and the lower end of the herringbone connecting rod will stretch the arm Stretch outwards, and at the same time, stretch the patient's teeth to facilitate oral examination and medicine feeding for medical staff. After the spreader is used and disinfected, the handle is rotated, and the relative action of the screw nut drives the herringbone connecting rod to move upward. , the two spreading arms are folded and merged under the upward pulling action of the herringbone connecting rod for next use.

Except the technical characteristics disclosed in the description of the present invention, all are well-known technologies of those skilled in the art.
