DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0022] Example

[0023] Reference Figures 1 to 4 The utility model provides a uterine probe for clinical use in obstetrics and gynecology, including: a probe body 1 and a pressure feedback part. The peripheral side of the probe body 1 is engraved with scales for detecting the depth of the uterus. The pressure feedback part is arranged on the probe body 1, and the pressure feedback part is used to detect the pressure of the probe body 1 on the uterus.

[0024] In a feasible embodiment, the pressure feedback unit can use a piezoresistive pressure sensor. The piezoresistive pressure sensor is a sensor made of the piezoresistive effect of single crystal silicon material and an integrated circuit. When the single crystal silicon material is subjected to force, the resistivity will change. At this time, an electrical signal proportional to the force change will be output through the measuring circuit. In this embodiment, the piezoresistive pressure sensor can be arranged at the front end or the rear end of the probe body 1, and the specific position can be set according to the actual application scenario. The piezoresistive pressure sensor detects the pressure value received by the front end of the suction probe body 1, and the output end of the pressure sensor is connected to the input end of the signal processing module, and the collected pressure signal is sent to the signal processing module for processing. Among them, the signal processor includes a filter and an analog-to-digital converter, the output end of the pressure sensor is connected to the input end of the filter, the output end of the filter is connected to the input end of the analog-to-digital converter, and the output end of the analog-to-digital converter is connected to the input end of the controller. The filter filters the pressure signal collected by the pressure sensor, and then the analog-to-digital converter converts the pressure signal from an analog signal to a digital signal. The digital signal intuitively reflects the pressure of the probe body 1 on the uterus.

[0025] In some other feasible embodiments, the pressure feedback part is a fiber optic sensor, and a Bragg grating for sensing the pressure value on the end of the probe body 1 is configured on the fiber optic sensor. During operation, an external light source enters the fiber optic sensor, and the light entering the fiber optic sensor enters the Bragg grating, and only the light whose central wavelength satisfies the Bragg equation can be totally reflected by the Bragg grating. When the end of the probe body 1 contacts the uterine wall, the Bragg grating will undergo a micro-deformation, changing the period of the Bragg grating, thereby causing a change in the wavelength of light. By collecting the reflected wavelength change information, the pressure value of the end of the probe body 1 is monitored in real time, and the pressure value information of the end of the probe body 1 touching the outside world is fed back to the operator, so that the operator can perform operations corresponding to the pressure value information.

[0026] In a feasible embodiment, the probe body 1 includes a barrel 12 and a probe head 11, and the probe head 11 includes a first end 111 and a second end 112 arranged opposite to each other in the axial direction, the first end 111 extends out of the barrel 12, and the second end 112 is inserted into the barrel 12. The probe head 11 can be displaced along the axial direction of the barrel 12, and the pressure feedback part is arranged on the second end 112. When the first end 111 is subjected to pressure, the probe head 11 is displaced and the pressure is transmitted to the pressure feedback part through the second end 112. In a more preferred embodiment, the barrel 12 is made of a bendable and deformable material so that different angles can be changed during use. In this embodiment, the pressure feedback part uses a strain gauge to detect pressure. The pressure feedback part includes an elastic element, and the pressure is measured by measuring the strain of the elastic element. According to different manufacturing materials, the strain element can be made of metal and semiconductor. When the first end 111 is subjected to pressure, the probe head 11 is displaced and the pressure is transmitted to the elastic element through the second end 112. When the elastic element is mechanically deformed, its resistance value changes, thereby detecting the pressure of the probe head 11. In this embodiment, the probe head 11 adopts a flexible rubber head, which can effectively improve the protection of the uterine probe body during use, and prevent the medical staff from inserting the uterine probe body into the patient's body. Due to the high hardness of the probe head 11, it will cause a certain degree of wear and tear on the patient's body tissue or stab the patient, causing secondary injury to the patient.

[0027] Specifically, the pressure feedback unit includes a spring 3 disposed in the barrel 12. In addition to detecting the pressure of the probe head 11, the spring 3 can also retract the probe head 11 into the barrel 12 when it touches the uterine wall, which can play a buffering role and avoid inadvertent perforation of the uterus.

[0028] In a feasible embodiment, it also includes a telescopic tube 4, and the cylinder 12 is defined as a first section 121 and a second section 122. One end of the first section 121 is provided with a probe and a pressure feedback part, and the other end is connected to the telescopic tube 4, and one end of the second section 122 is connected to the telescopic tube 4. In this embodiment, the telescopic tube 4 can effectively improve the flexibility of the probe body 1 itself, and the medical staff can adjust its length according to the patient's condition. At the same time, when the probe body 1 is extended into the patient's body, it can finely adjust its angle according to the patient's internal structure, so as to avoid damage to the patient when it is inserted straight into the patient's body, and it is also convenient for the medical staff to check.

[0029] In a feasible embodiment, it also includes an inflatable component, which is connected to the second section 122. The inflatable component controls the length of the telescopic tube 4 by inflating or deflating. Controlling the length of the telescopic tube 4 by inflating is highly flexible and easy to operate. It only needs to be inflated and deflated, which greatly improves the work efficiency of the operator. Specifically, the inflatable component includes an inflatable bag 51 and an air bag 52. The inflatable bag 51 is connected to the second section 122. The air bag 52 is accommodated in the second section 122. The inflatable bag 51 is communicated with the air bag 52. The inflatable bag 51 is used to inflate or deflate the air bag 52 so that the air bag 52 expands or contracts to the length of the telescopic tube 4. For example, a baffle is set in the second section of the cylinder, and the air bag is fixedly connected to the baffle. The expansion or contraction of the air bag can drive the second section to move, thereby compressing or extending the length of the telescopic tube.

[0030] In a feasible embodiment, the air bag 52 is arranged on the mounting ring 6, and the mounting ring 6 is detachably connected to the inflatable bag 51. Most of the existing clinical uterine probes are of an integrated structure and cannot be disassembled and replaced, which will cause a certain amount of resource waste and greatly increase the cost of medical examination. Since in the present application, the mounting ring 6 is detachably connected to the inflatable bag 51, it is convenient for medical staff to adjust and use it later, and it is also convenient for medical staff to replace it after use, which avoids resource waste and reduces the cost of use to a certain extent. In some other feasible embodiments, the detachable connection between the mounting ring 6 and the inflatable bag 51 is a threaded connection structure, a snap connection structure, a screw connection structure or a magnetic connection structure. In a preferred embodiment, a first external thread 61 is formed on the mounting ring 6, and a first internal thread matching the first external thread 61 is formed on the inflatable bag 51. The above-mentioned installation method can save installation time to a great extent.

[0031] Similarly, the mounting ring 6 is detachably connected to the barrel 12. This is convenient for medical staff to adjust and use it later, and it is also convenient for medical staff to change jobs after use, which avoids waste of resources and reduces the cost of use to a certain extent. In some other feasible embodiments, the mounting ring 6 is detachably connected to the barrel 12 by a threaded connection structure, a snap connection structure, a screw connection structure or a magnetic connection structure. In a preferred embodiment, a second internal thread 62 is formed on the mounting ring 6, and a second external thread 123 that matches the second internal thread 62 is formed on the barrel 12. The above-mentioned installation method can save installation time to a great extent.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
