Description

Technical Field

[0001] The invention relates to a surgical instrument, in particular to an open mouth bracket for adjusting the height and angle of an open mouth. Background Art

[0002] The mouth opener is a commonly used surgical auxiliary instrument in otolaryngology and dentistry. It is mainly used clinically to expose the surgical field of the oral cavity, pharynx and nasal cavity, such as tonsillectomy, lateral pharyngeal mass resection, palatopharyngealplasty, nasopharyngeal tumor resection, cleft palate repair, etc.

[0003] At present, during the above-mentioned surgery, the fixation of the mouth opener is generally fixed by using a McStaff stand, a hanging ring bracket or directly fixed by a medical assistant. McStaff stand fixation and hanging ring bracket fixation have the defects of easy slipping during fixation or difficult adjustment during surgery. And the direct gripping fixation of the medical assistant is very easy to cause fatigue over a long period of time, and the fixation effect of the mouth opener is very easy to be affected in a fatigued state.

[0004] Therefore, it is necessary to improve the existing mouth opener fixing bracket to ensure the fixing effect while facilitating real-time adjustment during the operation. Summary of the invention

[0005] The mouth opener bracket of the present invention is designed with a cantilever adjustment arm. During clinical use, the adjustment arm can be loosened by slightly adjusting the angle of the cantilever, and the height and angle of the mouth opener can be adjusted by moving it up and down. During clinical use, it not only has a good fixing effect, but also is very convenient to adjust.

[0006] The opener bracket of the present invention is characterized in that: the opener bracket 100 comprises a base 1, a support column 2, an adjustment arm 3 and an opener interface 4;

[0007] A. The lower end of the support column 2 is connected to the base 1;

[0008] B. An adjusting positioning hole 31 is provided at the proximal end of the adjusting arm 3, and the adjusting positioning hole 31 can slide on the supporting column 2 when in a relaxed state; and the opening device interface 4 is provided at the distal end of the adjusting arm 3.

[0009] The proximal end of the adjusting arm 3 of the opener bracket of the present invention is provided with an adjusting positioning hole 31, and the height and angle of the opener 200 connected to the opener interface 4 of the opener bracket 100 can be adjusted by sliding the adjusting positioning hole 31 up and down on the support column 2, which is very convenient to adjust during clinical use.

[0010] The adjusting arm 3 is a cantilever structure. The cantilever structure design is very simple and can minimize the obstruction and interference of the adjusting arm 3 on the surgical field of view.

[0011] When the distal end of the adjusting arm 3 is pressed downward, the adjusting positioning hole 31 of the adjusting arm 3 is locked, and the adjusting arm 3 cannot slide on the supporting column 2; when the distal end of the adjusting arm 3 is lifted upward, the adjusting positioning hole 31 of the adjusting arm 3 is loosened, and the adjusting arm 3 can slide on the supporting column 2.

[0012] The adjustment positioning hole 31 has two states: a locked state and a relaxed state. The diameter of the adjustment positioning hole 31 is slightly larger than the outer diameter of the support column 2. When the distal end of the adjustment arm 3 is pressed down, the edge of the adjustment positioning hole 31 bears against the outer surface of the support column 2, the adjustment arm 3 is in a locked state, and the opener 200 connected to the adjustment arm 3 is fixed. When the distal end of the adjustment arm 3 is lifted upward, the edge of the adjustment positioning hole 31 looks at the outer surface of the support column 2, and the adjustment arm 3 is in a relaxed state. At this time, the adjustment arm 3 can slide up and down along the support column 2, thereby adjusting the height and angle of the opener 200. Usually, the adjustment arm 3 is inclined upward at an angle β to the support column 2, and the adjustment positioning hole 31 is an oblique angle at an angle α to the adjustment arm 3. The slightly inclined upward design can make the adjustment arm 3 better fixed on the support column 2.

[0013] The mouth-opening device interface 4 is a hole-shaped structure with a positioning groove 41; the mouth-opening device interface 4 matches the mouth-opening device 200. The mouth-opening device interface 4 is a hole-shaped structure with a positioning groove 41, and the connector 2-1 of the mouth-opening device 200 can be directly inserted into the positioning groove 41 to form a connection, and when taking it out, the connector 2-1 can be directly taken out from the positioning groove 41. With this hole-shaped structure design, the connection and separation of the mouth-opening device 200 and the mouth-opening device bracket 100 are very convenient.

[0014] The support column 2 is detachably connected to the base 1. The detachable connection mode allows the support column 2 and the base 1 to be disassembled for cleaning, and the cleaning process is more convenient and more thorough.

[0015] The support column 2 is connected to the base 1 by a concave-convex snap-fit ​​connection or a threaded connection. The applicant only lists the above two detachable connection methods. In actual applications, technicians in this field can design different connection structures as needed without departing from the protection scope of this application.

[0016] A limiting mechanism 21 is provided at the upper end of the support column 2. The limiting mechanism 21 can prevent the adjustment arm 3 from being separated from the upper end of the support column 2. The outer portion of the limiting mechanism 21 is designed as a polygonal structure, and when the support column 2 is connected to the base 1, the limiting mechanism 21 can be easily rotated and used as a nut.

[0017] The proximal end of the adjusting arm 3 is also provided with a fixing mechanism 32. The fixing mechanism 32 can additionally fix the adjusting arm 3 to the supporting column 2, making the clinical use process safer.

[0018] The support column 2 is provided with anti-skid patterns 22. The anti-skid patterns 22 can further increase the friction between the adjustment positioning hole 31 and the support column 2, and enhance the connection reliability between the adjustment arm 3 and the support column 2.

[0019] The anti-skid pattern 22 is a spiral structure. When the adjusting arm 3 slides up and down along the supporting column 2, the adjusting arm 3 can slide up and down along the anti-skid pattern of the spiral structure, and the sliding of the adjusting arm 3 is smoother.

[0020] During clinical use, the mouth-opening device support frame 100 is first placed on the front chest of the human body, the working part of the mouth-opening device 200 is placed in the oral cavity, and the opening degree of the mouth-opening device 200 is adjusted. Then the joint 2-1 of the mouth-opening device 200 is inserted into the positioning groove 41 of the mouth-opening device interface 4, the adjustment arm 3 is adjusted to a suitable height, and then the adjustment arm 3 is pressed downward to lock the adjustment arm 3. During the operation, when the angle and position of the mouth-opening device 200 need to be adjusted, the adjustment arm 3 is lifted upward, and then the adjustment arm 3 is slid up and down along the support column 2 to a suitable position, and then the adjustment arm 3 is pressed downward to lock the adjustment arm 3.

[0021] The mouth-opening device support frame of the present invention comprises a base 1, a support column 2, an adjustment arm 3 and an mouth-opening device interface 4. The lower end of the support column 2 is installed on the base 1, the proximal end of the adjustment arm 3 is provided with the positioning adjustment hole 31, and the distal end is provided with the mouth-opening device interface 4. The adjustment arm 3 is connected to the support column 2 through the positioning adjustment hole 31. When the adjustment arm 3 is in a relaxed state, the adjustment arm 3 can slide up and down along the support column 2, thereby adjusting the angle and opening degree of the mouth-opening device 200 connected to the adjustment arm 3. The mouth-opening device support frame of the present invention can switch the locking or relaxation state of the adjustment arm 3 by simply lifting or pressing down the adjustment arm 3, thereby conveniently adjusting the position of the adjustment arm 3 on the support column 2, so as to achieve the purpose of adjusting the mouth-opening device 200, and the clinical use process is very simple.

The detachable connection method allows the support column 2 and the base 1 to be disassembled for cleaning, and the cleaning process is more convenient and more thorough. The support column 2 can also be non-detachably connected to the base 1, or technicians in this field can design other detachable structures as needed, such as a concave-convex card-fitting structure, etc., to connect the support column 2 to the base, which does not deviate from the protection scope of this application, and the applicant will not give examples one by one here.

[0044] refer to Figure 1 A limiting mechanism 21 is provided at the upper end of the support column 2. The limiting mechanism 21 can prevent the adjusting arm 3 from being separated from the upper end of the support column 2. The outer portion of the limiting mechanism 21 is designed as a polygonal structure.
