Description

A plastic endometrial sampler

Technical Field

The utility model relates to the technical field of medical devices, in particular to a plastic endometrial sampler.

Background Art

Disposable endometrial samplers are commonly used tools in the field of gynecology and reproductive medicine. Endometrial tissue can be obtained by aspiration of the endometrium, and pathological examination or microbiological examination can be performed to clarify endometrial lesions and assist in the etiology diagnosis and treatment effect evaluation of infertile patients. This operation method is simple and quick in most cases and is widely used in clinical practice.

However, in clinical practice, patients with difficult operation are often encountered, such as extremely curved uterine position, cervical stenosis, cervical curvature, cervical deformity, etc. When using traditional non-disposable uterine cavity probes and uterine curettes, due to the bendable and fixed characteristics of their metal materials, the operating doctor can bend and shape the probes and curettes according to the actual uterine position and curvature of the patient, making it easier for the instruments to enter the uterine cavity. However, the operation steps of traditional instruments are complicated and the patient feels obvious pain; and because the metal material is too hard, it is easy to increase corresponding complications such as uterine injury or perforation during the operation; non-disposable instruments also have cross-contamination risks, high disinfection requirements, and long-term use. Wear and tear. Therefore, disposable plastic endometrial samplers are often used in clinical practice. However, the commonly used disposable endometrial samplers are made of ordinary plastic materials, which have poor plasticity. Even if they have a certain degree of bendability, they are difficult to shape, often rebound and reset in a short time, and there is no obvious direction and angle mark on the surface of the sampler. When taking samples from patients with special cervical morphology or curvature, clinicians often need to make multiple fine-tuning explorations of the direction of the cervix and uterus based on their experience. During this process, the shape of the sampler is difficult to maintain, and there are no obvious signs to assist in identification when the direction changes, making the operation more difficult and time-consuming. Patients often experience obvious pain during the operation, and the risks of bleeding, infection, etc. also increase accordingly.

Therefore, a new type of disposable endometrial sampler is needed clinically, which has a certain degree of softness, can be shaped and formed according to actual clinical needs, and has obvious direction markings to facilitate fine-tuning of the instrument angle during operation.

Summary of the invention

In order to overcome the technical problem that traditional disposable endometrial samplers cannot be shaped according to the actual conditions of the patient, the utility model provides a plastic endometrial sampler. The plastic endometrial sampler can facilitate clinicians to adjust the shape and direction of the operating instrument according to the actual shape of the patient's uterus and cervix, thereby reducing the difficulty of the operation and reducing the patient's pain and the risk of complications.

The utility model discloses a plastic endometrial sampler, which is characterized in that it comprises an inner core, a sleeve and an angle indicator disk; the inner core is sleeved in the sleeve, and the inner core can slide in the sleeve; the angle indicator disk is fixedly installed at the tail of the sleeve; the surface of the angle indicator disk is provided with angle scales; the sleeve is made of a transparent material with flexibility and plasticity.

When using the plastic endometrial sampler, since the inner core and the sleeve have certain flexibility and plasticity, the operator can adjust the bending direction and amplitude of the endometrial sampler according to the actual physiological curvature of the patient's uterus, so as to facilitate the device to enter the patient's uterus; at the same time, in the process of the operator operating the endometrial sampler to enter the patient's uterus, it is necessary to make multiple fine adjustments and explorations on the direction of the cervix and uterus. In this process, by observing the difference between the position of the angle indicator disk and the initial position, a rough judgment can be made on the direction of the endometrial sampler, so that the endometrial sampler can be inserted more accurately and efficiently, and the sampling can be carried out accurately to avoid mis-taking or missing. The plastic endometrial sampler is especially useful for patients with special uterine and cervical positions and/or bending angles, and is more conducive to finding the relative position of the sampler, the cervix, and the uterine cavity, significantly reducing the patient's pain and operation time, and reducing the risk of related complications.

Furthermore, the sleeve is made of high molecular weight polyvinyl chloride.

Furthermore, the diameter of the angle indicating disc is 20 mm.

Furthermore, a piston ring is provided at the end of the inner core, and the piston ring is tightly matched with the tube wall of the sleeve; there is a preset distance between the end of the inner core and the end of the sleeve. The provision of the piston ring facilitates the formation of negative pressure in the sleeve when operating the endometrial sampler, and the preset distance between the end of the inner core and the end of the sleeve can ensure that the end of the sampling sleeve is softer and easier to enter the uterus.

Furthermore, the preset distance is 5 mm.

Furthermore, an operating handle is arranged at the tail of the inner core; and the surface of the operating handle has anti-skid patterns. The arrangement of the operating handle and the anti-skid patterns facilitates operation by the user.

Furthermore, the surface of the sleeve is provided with a plurality of scale bars, and the tail of the sleeve has a limit portion. The scale bars can reflect the depth of the sampling tube entering the cervix, and when the top of the sampling tube reaches the bottom of the uterus, the scale on its surface is the depth of the uterine cavity. When the piston ring on the inner core moves to the limit portion, it will not be able to continue to move outward, so the limit portion can prevent the operator from completely pulling the inner core out of the cavity of the sampling sleeve.

Furthermore, the distance between each of the scale bars is 1 cm.

Furthermore, the plastic endometrial sampler also includes a tail decoration piece, which is fixedly connected to the tail of the sleeve and wraps a portion of the inner core.

During the operation, the surgeon adjusts the direction and amplitude of the endometrial sampler according to the actual physiological curvature of the patient's uterus and cervix, and then slowly inserts the endometrial sampler from the cervical opening. When the outer sleeve is inserted into the uterine fundus, the surgeon observes the indication of the angle indicator disk, determines the direction of the endometrial sampler and adjusts it. The inner core is moved along the lumen direction of the sleeve by operating the handle to form a negative pressure in the lumen of the sleeve to achieve sampling. At the same time, the sampling tube is moved back and forth several times as needed, and the sleeve is rotated so that endometrial tissues of different walls can be sucked into the lumen as needed.

The utility model provides a plastic endometrial sampler, which allows the operating doctor to adjust the bending position and angle of the sampling tube according to the actual situation of the patient, and clearly understand the change in the rotation angle of the sampling tube, so as to insert the sampling tube more accurately and efficiently. Especially for patients with special uterine and cervical positions and/or bending angles, it is more conducive to finding the relative position of the sampler and the cervix and uterine cavity, significantly reducing the patient's pain and operation time, and reducing the risk of related complications.
