Description

Fixed multi-functional oval pincers of unilateral buckle of long arc for gynaecology and obstetrics

Technical Field

The utility model relates to the field of medical instruments, in particular to a long-arc single-side buckle fixed type multifunctional oval forceps for obstetrics and gynecology.

Background

An oval forceps is one of medical instruments commonly used in gynecological operations, and is generally used for holding medical tools or detecting the internal conditions of a uterine cavity and clamping tissue structures in a patient while performing an operation. The prior art comprises two articulated clamp bodies, each of which is provided with a strip with saw teeth, which are engaged and fixed when they are brought close to each other. The structure can keep the distance between the two clamp bodies to fix the clamping object and prevent the clamping object from falling off. However, since there are two card strips, when the card strip is used for a long time or damaged by external force, the engagement structure cannot be used continuously as long as there is a card strip whose position changes, and the engagement can be realized continuously by repeatedly adjusting the position relationship between the two card strips. Therefore, a novel long-arc unilateral buckle fixed multifunctional oval forceps for obstetrics and gynecology department is needed urgently.

For example, chinese patent publication No. CN209916151U discloses a long arc single-side buckle fixed multifunctional oval forceps for obstetrics and gynecology department. The multifunctional oval forceps comprise a first forceps arm and a second forceps arm which are hinged to each other, a first object holding ring and a first handle are arranged at the two ends of the first forceps arm respectively, a second object holding ring and a second handle are arranged at the two ends of the second forceps arm respectively, a toothed locking rod capable of penetrating into the second forceps arm is fixed to the bottom of the first forceps arm, a plurality of clamping teeth are uniformly arranged on the side wall of the toothed locking rod at intervals, and the clamping teeth are matched with the side wall of the second forceps arm in a clamping mode. The utility model has the advantages of fixing clamping, adjusting the operation range and reducing injury to the patient. However, the utility model still has the following technical disadvantages: the toothed locking rod is provided with a plurality of clamping teeth, so when the first clamp arm and the second clamp arm are closed, the clamping teeth on the first clamp arm can still be clamped with the second clamp arm; meanwhile, when the first forceps arm and the second forceps arm are opened or closed, hands of medical staff are easy to shake due to the existence of the clamping teeth, and metal impact sound is easy to generate between the clamping teeth and the first forceps arm or the second forceps arm, so that the medical staff is troubled. Therefore, in view of the deficiencies of the prior art, it is necessary to adopt a new technical solution to control or fix the opening angle of the first and second clamp arms.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the above, however, the present invention is by no means free of the features of the prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.

Multifunctional oval forceps according to claim 5, characterized in that the side of the clamping part (8) for the medical tool and/or the body tissue specimen is provided with anti-slip threads in such a way that the friction between the clamping part and the medical tool and/or the body tissue specimen can be increased.

7. The multifunctional oval forceps according to claim 6, characterized in that the first forceps arm (1) and the second forceps arm (2) each comprise a telescopic rod (101) and a sleeve rod (102), and the sleeve rod (102) is sleeved outside the telescopic rod (101) and can move towards or away from the connecting part (3) along the axial direction of the telescopic rod (101) to adjust the total length of the first forceps arm (1) or the second forceps arm (2).

8. Multifunctional oval forceps according to claim 7, characterized in that a first snap element (103) is movably connected to the end surface of the sleeve rod (102) close to the telescopic rod (101) inwards in the radial direction of the sleeve rod (102), and that the side of the telescopic rod (101) facing the first snap element (103) is provided with a plurality of first through holes (104) matching the first snap element (103), wherein the first snap element (103) is configured to be able to press the first snap element (103) inwards in the radial direction of the sleeve rod (102) such that the first snap element (103) is inserted into the first through hole (104) to prevent the telescopic rod (101) from moving in the axial direction of the sleeve rod (102) within the sleeve rod (102).

9. The multifunctional oval forceps according to claim 8, characterized in that the parts of the telescopic rod (101) between the clamping parts (8) and the connecting parts (3) are respectively arc-shaped structures, so that two planes on which the clamping parts (8) of the first forceps arm (1) and the second forceps arm (2) respectively are located can be parallel to each other when the clamping parts (8) clamp medical tools and/or human tissue specimens, wherein the arc degree corresponding to the arc-shaped structures of the telescopic rod (101) between the clamping parts (8) and the connecting parts (3) ranges from ten degrees to thirty degrees.

10. Multifunctional oval forceps according to claim 8, characterized in that one of the hand-held parts (6) is provided with an opening in the shape of an ellipse in such a manner that at least one finger other than the human thumb can be inserted into the hand-held part (6), the other hand-held part (6) is provided with an opening in the shape of an oval line, the peripheral outer walls of the hand-held parts (6) are each provided with a rounded surface,

the radian radius corresponding to the first end part, far away from the connecting part (3), of the handheld part (6) with the oval opening is larger than the radian radius corresponding to the second end part, close to the connecting part (3), of the handheld part, so that the oval opening of the handheld part (6) can be attached to the surface contour of the root of the thumb of a human body, and the discomfort of inserting the thumb of a user into the opening is relieved.
