Description

Detachable split-type ultrasonic probe fixed by plug

technical field

The utility model relates to the technical field of ultrasonic monitoring uterine cavity surgical instrument for obstetrics and gynecology, which is an extended product of B-ultrasound, in particular to a split-type ultrasonic probe which is fixed by a bolt and can be disassembled freely.

Background technique

In the field of obstetrics and gynecology surgery, in order to solve the problem of accurate and effective real-time monitoring and guidance of the operation process during the operation process of obstetrics and gynecology transvaginal uterine cavity surgery, increase the safety and success rate of the operation, and reduce the pain of patients, To shorten the operation time, various medical clinical institutions and medical device manufacturers have proposed many different solutions, mainly including two categories. The first category is designed using the principle of optical imaging, which is clinically called endoscopic or microtube type. , its weakness is that the image will be blurred when the optical lens is stained with blood or water vapor, and the image will not achieve the expected effect as the bleeding contaminates the lens. It also brings physical and psychological pain to patients. The second category is to use the principle of ultrasound imaging to monitor the operation process in real time through the vagina with a B-ultrasound probe, which is also called "superconducting visualization" in clinical practice. The ultrasonic probe of this type of equipment does not need to enter the uterine cavity, and only needs to be isolated with a disposable rubber sleeve during use, without complicated disinfection process. At present, in order to make the uterine cavity operation safe and effective, and at the same time not occupy the operation space to the greatest extent, various medical institutions and medical device manufacturers have proposed various combinations of transvaginal probes and vaginal dilators, such as: Patent No. 200420012332.3 The "B-mode Ultrasonic Monitor for Female Family Planning Operations" and the "Intravaginal Ultrasound Probe for Gynecological Surgery Monitoring" with patent number 200620076977.2 (later applied for a design patent, patent number 200730026672.0).

Among them, the patent No. 200420012332.3 "Female Family Planning Operation B-type Ultrasonic Monitor" is combined with a transvaginal probe and a vaginal dilator in a clamping manner. It is clamped after the ultrasonic probe is covered with a sterile rubber sleeve On the upper or lower wing of the vaginal dilator, it enters the female vaginal cavity for real-time ultrasound monitoring of the operation process. And the patent No. 200730026672.0 "intravaginal ultrasound probe for gynecological surgery monitoring" adopts a transvaginal probe to fit the probe on the lower wing of the vaginal dilator in an anastomotic manner, and the transvaginal probe must be covered with a sterile rubber sleeve.

Since uterine cavity surgery in obstetrics and gynecology and the surgical instruments used must be sterile, the combination of the probe and the dilator in the patent No. 200420012332.3 "B-type ultrasonic monitor for female family planning surgery" is carried out in a clamping manner, while At present, the aseptic rubber sleeves actually used in various medical institutions are generally sterilized condoms, but the clip connection is a rigid combination method with a small contact surface between the two objects. The combined method causes the thinner condom to rupture, resulting in surgical infection of the patient; the patent No. 200730026672.0 "Intravaginal Ultrasound Probe for Gynecological Operation Monitoring" adopts a transvaginal probe covered with a sterile rubber sleeve and then attached to the vaginal dilation The lower wing of the vaginal dilator itself has no physical connection between the two. During the operation, in order to keep the relative position of the transvaginal probe and the vaginal dilator unchanged, the upper and lower wings of the vaginal dilator must be opened as much as possible, relying on the female vagina itself. The elasticity fits the probe to the dilator, and the transvaginal probe itself has a certain thickness, which brings physical pain to patients, especially physical and psychological pain to young women.

Contents of the invention

The purpose of this utility model is to provide a kind of aseptic disinfection rubber sleeve which is not easy to be damaged, and the transvaginal probe is connected firmly with the vaginal dilator. It relieves the patient's physical pain and is a more humanized B-ultrasound probe.

In order to achieve the purpose of the above-mentioned utility model, the utility model provides a plug-type fixed and freely detachable split-type ultrasonic probe, including an ultrasonic probe and a vaginal dilator. The wing or the lower wing has a concave slot that matches the shape of the protruding pin. When in use, the protruding pin of the ultrasonic probe is inserted into the slot on the vaginal dilator to make the two firmly connected. When disassembling, the protruding pin of the ultrasonic probe The pin is pulled out of the slot on the vaginal dilator.

The protruding pins can be distributed on both sides, bottom or top of the probe, can be protruding on both sides, or can be protruding on one side, and the protruding pins on both sides can be symmetrical or asymmetrical. The matching concave slot can be a hole-shaped jack, as long as it is any shape that can make the raised plug tightly combined with the concave slot. Preferably, protruding pins are provided on both sides of the bottom of the probe, which is more compact and simple in structure.

A detachable split-type ultrasonic probe fixed by a bolt, comprising an ultrasonic probe and a vaginal dilator, the upper or lower wing of the vaginal dilator has a protruding pin, and the ultrasonic probe has a Matching concave slot, when in use, the protruding pin on the vaginal dilator is inserted into the slot of the ultrasonic probe, so that the two are firmly connected. When disassembling, pull out the protruding pin on the vaginal dilator from the slot of the ultrasonic probe. Can.

The protruding pins can be distributed on the upper or lower wings of the vaginal dilator. They can be protruding on both sides or on one side. The protruding pins on both sides can be symmetrical or asymmetrical. The matching concave slot can be a hole-shaped jack, and the jack can be located in the middle of the ultrasonic probe, as long as it is any shape that can make the raised pin and the concave slot tightly combined.

The detachable split-type ultrasonic probe fixed by a bolt is characterized in that the shape of the protruding bolt is triangular.

The detachable split-type ultrasonic probe fixed by a bolt is characterized in that the shape of the protruding bolt is U-shaped.

The detachable split-type ultrasonic probe fixed by a bolt is characterized in that the shape of the protruding bolt is trapezoidal.
