Description

Technical Field

[0001] This utility model relates to the field of uterine probe technology, and in particular to a novel dual-purpose uterine probe. Background Technology

[0002] A uterine probe is a basic gynecological instrument mainly used to explore the depth, direction, and curvature of the uterine cavity before intrauterine surgeries (such as induced abortion, curettage, and insertion / removal of intrauterine devices), providing crucial information for subsequent surgical procedures.

[0003] Current uterine probes are typically only a single straight or curved probe. Due to significant individual differences in the shape and position of the uterus (e.g., anteverted, mid-position, retroverted), surgeons often need to pre-select a probe based on experience. Inappropriate selection necessitates changing instruments during the procedure, leading to reduced surgical efficiency and increased risk of infection for the patient.

[0004] Furthermore, traditional uterine probes are rigid metal rods, and their operation relies entirely on the doctor's feel and experience. During the examination, if resistance is encountered or the doctor applies the wrong force, there is a potential risk that the probe tip could puncture the uterine wall. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a novel dual-purpose uterine probe that can adapt to different uterine shapes and has a buffering and damage prevention function, in order to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel dual-purpose uterine probe, characterized by comprising: A hand handle having a first end and a second end that are positioned opposite to each other; A straight probe section is disposed at the first end of the hand handle; A curved probe portion is disposed at the second end of the hand handle; The curved probe section includes a first axial section and a second axial section. The first axial section is coaxially arranged with the straight probe section, and the axis of the first axial section and the axis of the second axial section have an included angle of 20° to 45°. Both the straight probe section and the curved probe section have scale markings on their outer peripheral surfaces.

[0007] The technical problem to be solved by this utility model can be further achieved through the following steps: the ends of the straight probe and the curved probe that are away from the handle are both provided with flexible ends on the same axis; a buffer mechanism is provided inside the handle to prevent the probe from being excessively inserted and damaging the endometrium.

[0008] The technical problem to be solved by this utility model can also be further achieved through the following steps: a cavity is provided inward on the side of the hand handle, and a partition is fixedly provided in the middle of the cavity. The partition divides the cavity into two buffer chambers, and each buffer chamber is provided with a through hole at the end away from the partition for a straight probe or a curved probe to enter. The buffer mechanism includes buffer components respectively set in two buffer chambers. The buffer components include a slide rail set in the buffer chamber along the axial direction of the straight probe part, a slide seat slidably mounted on the slide rail, and a deformation energy-absorbing element set between the slide seat and the partition. The slide seat is fixedly connected to the straight probe part or the curved probe part.

[0009] The technical problem to be solved by this utility model can be further achieved through the following steps: the end face of the slide away from the partition is provided with an internally threaded mounting hole, and the ends of the straight probe part and the curved probe part adjacent to the hand handle are both coaxially fixed with external threads that cooperate with the mounting hole.

[0010] The technical problem to be solved by this utility model can be further achieved through the following steps: the through hole is a guide hole corresponding to the outer diameter of the straight probe part or the curved probe part; the deformation energy absorbing element is a buffer spring.

[0011] The technical problem to be solved by this utility model can be further achieved through the following steps: the ends of the straight probe part and the curved probe part away from the handle are both fixedly provided with screws, the end of the flexible end near the handle is provided with a screw hole that cooperates with the screws, and the other end of the flexible end is set as a hemisphere.

[0012] The technical problem to be solved by this utility model can be further achieved through the following steps, wherein the outer diameters of the straight probe part and the curved probe part are equal.

[0013] The technical problem to be solved by this utility model can be further achieved through the following steps: a dust cover is provided at the opening of the cavity of the hand handle, and anti-slip textures are provided on the outer surfaces of both the hand handle and the dust cover.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By integrating the straight and curved probe parts into one unit, medical personnel can directly select the appropriate probe part for exploration according to the uterine shape and operational needs during the operation, effectively avoiding instrument replacement due to improper selection, and effectively improving the continuity and efficiency of the surgical procedure; when the probe tip touches the fundus of the uterus or encounters abnormal resistance, its built-in buffer mechanism can generate buffer displacement by means of spring compression deformation to limit excessive probe insertion, effectively reducing the risk of uterine wall damage; in addition, the flexible tip set at the distal end of the probe can gently contact the endometrial tissue, effectively reducing patient discomfort and improving the comfort of diagnosis and treatment while ensuring operational accuracy.

[0016] The specific technical solutions of this utility model are further described below to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

Therefore, they should not be construed as limitations on the utility model.

[0018] Please refer to Figure 1-4 A novel dual-purpose uterine probe includes a handle, a straight probe portion, and a curved probe portion. The handle has a first end and a second end disposed opposite to each other. The straight probe portion is disposed at the first end of the handle, and the curved probe portion is disposed at the second end of the handle. The curved probe portion includes a first axial segment and a second axial segment. The first axial segment is coaxially disposed with the straight probe portion, and the axis of the first axial segment and the axis of the second axial segment have an included angle of 20° to 45°. Figure 4 This design allows the probe to better conform to and explore uterine cavities with physiological anteflexion or retroflexion, improving measurement accuracy and ease of operation. Both the straight and curved probe sections have graduated markings on their outer circumference for medical personnel to identify and record the insertion depth.

[0019] The handle, straight probe, and curved probe are all made of medical-grade stainless steel; the cross-sections of the straight and curved probes are both cylindrical; the first axial section of the curved probe is connected to the handle; thus, two different probe shapes are integrated into one, allowing medical personnel to flexibly select the appropriate probe based on the uterine shape (such as anteverted, mid-position, or retroverted) without changing instruments, effectively improving surgical efficiency.

[0020] Furthermore, both the straight probe section and the curved probe section have flexible tips coaxially arranged at their ends away from the handle; the handle is provided with a buffer mechanism to prevent excessive insertion of the probe and damage to the endometrium.

[0021] The flexible tip is made of medical-grade silicone, which replaces traditional rigid contact with gentle physical contact, effectively reducing irritation and potential damage to the endometrium and improving patient comfort. The buffer mechanism provides passive safety protection, preventing excessive probe insertion and uterine perforation risks caused by improper operation.

[0022] Furthermore, a cavity is provided on the side of the hand handle, and a partition is fixedly provided in the middle of the cavity. The partition divides the cavity into two buffer chambers, and each buffer chamber is provided with a through hole at the end away from the partition for a straight probe or a curved probe to enter. The buffer mechanism includes buffer components respectively set in two buffer chambers. The buffer components include a slide rail set in the buffer chamber along the axial direction of the straight probe part, a slide seat slidably mounted on the slide rail, and a deformation energy-absorbing element set between the slide seat and the partition. The slide seat is fixedly connected to the straight probe part or the curved probe part.

[0023] There are two slide rails, which are fixedly bonded to the top and bottom surfaces of the buffer chamber respectively. When the probe tip touches the fundus of the uterus or encounters abnormal resistance, the pressure is transmitted to the slide block through the straight probe part or the curved probe part, which drives the slide block to compress the spring and move backward along the slide rail. This buffer displacement actively absorbs energy and limits the further penetration of the probe, thereby achieving passive safety protection.

[0024] Furthermore, the slide block has a threaded mounting hole on its end face away from the partition, and both the straight and curved probe parts have coaxially fixed external threads that mate with the mounting hole at their ends near the handle. The straight and curved probe parts are detachably mounted on the slide block via threads, effectively reducing the space occupied when not in use and facilitating carrying and storage.

[0025] Furthermore, the through hole is a guide hole corresponding to the outer diameter of the straight probe section or the curved probe section, which is used to enhance the axial stability of the straight probe section and the curved probe section; the deformation energy absorption component is a buffer spring, which ensures reliable buffering performance while having better economic efficiency.

[0026] Furthermore, both the straight probe section and the curved probe section are fixedly provided with screws at the ends away from the handle, and the flexible end is provided with a screw hole that mates with the screw at the end near the handle. Installation and removal can be achieved by screwing, ensuring that the flexible end can be handled separately if damaged. The other end of the flexible end is set as a hemispherical shape to improve patient comfort.

[0027] Furthermore, the outer diameters of the straight probe section and the curved probe section are equal, ensuring that the two types of probes have consistent feel and passability during operation.

[0028] Furthermore, a dust cover is provided at the opening of the cavity of the hand handle, and the outer surfaces of both the hand handle and the dust cover are provided with anti-slip textures (not shown in the figure) to ensure a stable grip even in a humid surgical environment.

[0029] Working principle: When using this invention, medical personnel first select the straight or curved probe part at the corresponding end of the handle based on the patient's uterine position (e.g., preliminary judgment by clinical palpation or ultrasound). If the uterus is in a mid-position or anteverted, a straight probe part can be used; if the uterus is retroverted, a curved probe part is preferred, as the specific angle of its second axial segment can naturally conform to the curvature of the uterine cavity.

[0030] During the slow insertion of the selected probe into the uterine cavity, medical personnel can read the insertion depth at any time through the scale markings on its outer surface. When the probe tip (i.e., the flexible end) touches the fundus of the uterus or encounters abnormal resistance, axial pressure is transmitted through the probe to the slide block, driving the slide block to move backward along the slide rail and compress the buffer spring. The compression deformation of the buffer spring generates a buffer displacement to limit excessive probe insertion and effectively avoid mechanical damage to the uterine wall.

[0031] Throughout the procedure, the flexible silicone tip gently contacts the endometrium, effectively reducing patient discomfort. After use, the probe can be unscrewed and stored separately from the handle, saving space and facilitating thorough cleaning and disinfection of all components.

[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
