Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a multi-angle probe device that can be flexibly operated in hysteroscopic surgery. Background Art

[0002] Hysteroscopic surgery is a minimally invasive surgical technique that is mainly used to diagnose and treat various diseases inside the uterus. It enters the uterine cavity through the vagina and cervix and has the advantages of less trauma and quick recovery. The hysteroscope is a slender instrument equipped with a light source and a camera that can magnify the situation inside the uterus and display it on a monitor, allowing the doctor to clearly observe the structure inside the uterine cavity. When performing surgery on the patient, the probe will not be easy to observe due to tissue obstruction, and the probe needs to be converted to multiple angles so that the doctor can observe better and operate faster and more accurately.

[0003] In the existing patent CN101912305A, a hard microwave hysteroscope system is disclosed, which includes a hard hysteroscope and a cold light source host, a camera host, and a monitor connected to the hard hysteroscope. The hard hysteroscope is provided with a microwave knife operating device for cooperating with the treatment, and a microwave knife system host used in conjunction with the microwave knife operating device. The present invention can be divided into two types: separate type and integrated type according to the relationship between the microwave knife operating device and the hard hysteroscope. Since the microwave probe is a new type of medical equipment that uses microwave energy for local heating to treat a variety of diseases, it has a wide range of applications, significant efficacy, safety and no side effects. The present invention introduces advanced microwave technology into hysteroscopic surgery, uses the advantages of microwave technology to cooperate with hysteroscopic surgery, and achieves the superposition of hysteroscopic diagnosis and microwave therapeutic effects, which can improve the cure rate and accuracy of the surgery, so as to achieve the purpose of reducing the recurrence rate and improve medical quality and medical safety.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a multi-angle probe device for flexible operation in hysteroscopic surgery of the present invention, the sliding assembly 10 includes a sliding block 1001 arranged on a support plate 404, the sliding block 1001 passes through the end cover 2, a sliding rod 1002 passing through the end cover 2 is arranged on the sliding block 1001, and a sliding spring 1003 mounted on the outer ring of the sliding rod 1002 is arranged between the inner wall of the end cover 2 and the sliding block 1001.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a multi-angle probe device that can be flexibly operated in hysteroscopic surgery of the present invention, the clamping assembly 11 includes a toothed slot 1101 opened in the end cover 2, and the end of the sliding rod 1002 is provided with a limit block 1102 adapted to the toothed slot 1101, and the limit block 1102 is provided with a clamping tooth 1103 that meshes with the toothed slot 1101, and the clamping tooth 1103 is elastic.

[0045] Working principle: The hysteroscope body 1 is connected to relevant equipment. When operating on a patient, the medical staff holds the handle of the hysteroscope body 1, drives the end cover 2, the probe outer cylinder 301, the probe inner cylinder 303 and the connecting rod 302 to probe into the patient's body, so that part of the camera probe 602 can shoot the environment inside the body. The medical staff observes the situation inside the body, and passes the scalpel and other tools through the hysteroscope body 1, the end cover 2 and the probe inner cylinder 303 until the scalpel enters the position of the lesion photographed by the camera probe 602. The medical staff uses the scalpel to operate on the patient;

[0046] When tissue obstruction occurs, the operating rod 701 is pushed, and the operating rod 701 drives the negative pressure cylinder 801, the negative pressure piston 802, the threaded rod 803 and the drainage tube 804 to move forward. At the same time, the operating rod 701 drives the support ring 403 and the support plate 404 to move forward, forcing the support inner rod 402 to slide in the support outer rod 401. The movement of the support plate 404 drives the sliding block 1001 and the sliding rod 1002 to move, so that the sliding spring 1003 extends, and the sliding rod 1002 drives the limit block 1102 to move, so that the latching tooth 1103 is engaged with the tooth-shaped latching groove 1101. Since the latching tooth 1103 is elastic, when force is applied, the latching tooth 1103 will be deformed, and when force is not applied, the latching tooth 1103 will be stuck in the tooth-shaped latching groove 1101 to form a latching effect;

[0047] The support ring 403 drives the rotating tube 501, the connecting column 502, the rotating disk 503, the supporting tube 504 and the rotating connecting block 505 to move forward, forcing the supporting tube 504 to drive the elastic tube 601 and the protective sleeve 603 to move forward in the rotating space between the outer tube 301 and the inner tube 303, until the elastic tube 601 and the protective sleeve 603 are separated from the rotating space. At this time, the elastic tube 601 and the protective sleeve 603 extend out of the rotating space, and the elastic tube 601 loses its restraint, causing the elastic tube 601 to return to its original state, so that the elastic tube 601 The elastic tube 601 is opened in an arc shape, forcing the elastic tube 601 and the protective sleeve 603 to automatically stretch the surrounding tissues, forcing the camera probe 602 to be completely exposed in the human body, and realizing the annular non-dead angle shooting of the lesion site; at this time, after the position of the camera probe 602 is stabilized, no force is applied to the operating rod 701, so that the support plate 404 and the support ring 403 are located at a certain position, so that the locking teeth 1103 are located in a tooth-shaped locking groove 1101 at a certain place to form a locking connection, thereby avoiding the free movement of the camera probe 602 and improving the stability of the device;

[0048] At this time, the camera probe 602 is extended. According to the needs of the medical staff, when it is necessary to adjust the angle of the camera probe 602, due to the position of the camera probe 602 being clamped, the operating rod 701 is rotated, and the operating rod 701 rotates to drive the negative pressure cylinder 801 to rotate. At the same time, the operating rod 701 rotates to drive the active bevel gear 702 to rotate, and the active bevel gear 702 rotates to drive the driven bevel gear 703 to rotate, so that the driven bevel gear 703 rotates to drive the rotating disk 503 to rotate, and the rotating disk 503 rotates to drive the connecting column 502 to rotate, and the connecting column 502 rotates to drive the rotating tube 501 to rotate, and the rotating tube 501 rotates to drive the support tube 504 to rotate in the rotation space between the outer cylinder 301 and the inner cylinder 303. The support tube 504 drives the elastic tube 601 and the camera probe 602 to rotate to a reasonable angle, thereby effectively and quickly avoiding the obstruction of the tissue, and achieving the effect of multi-angle adjustment of the camera probe 602.

[0049] When encountering body fluid obstruction, for example, the body fluid and the elastic tube 601 have a certain angle, and the body fluid needs to be processed at this time, the operation rod 701 rotates to drive the active bevel gear 702 to rotate, and the active bevel gear 702 rotates to drive the driven bevel gear 703 to rotate, so that the driven bevel gear 703 rotates to drive the rotating disk 503 to rotate, the rotating disk 503 rotates to drive the connecting column 502 to rotate, the connecting column 502 rotates to drive the rotating tube 501 to rotate, and the rotating tube 501 rotates to drive the support tube 504 to rotate an angle in the rotating space between the outer cylinder 301 and the inner cylinder 303, forcing the suction nozzle 904 to rotate to below the body fluid, and the elastic tube 601 is arc-shaped. At this time, when the elastic tube 601 is located below the body fluid, the suction nozzle 904 is forced to be located below the body fluid, and the camera probe 602 is located above the body fluid, avoiding contamination of the camera probe 602;

[0050] When aspirating liquid, the threaded rod 803 is rotated to make the threaded rod 803 away from the end cover 2, forcing the threaded rod 803 to drive the negative pressure piston 802 to move in the negative pressure cylinder 801, so that negative pressure is formed in the negative pressure cylinder 801, so that the body fluid is introduced into the negative pressure cylinder 801 through the suction nozzle 904, the elastic tube 601, the support tube 504, the rotating tube 501, the rotating connecting block 505, the connecting tube 902, the connecting block 901, and the input tube 903 in sequence, and the negative pressure cylinder 801 is drained through the drainage tube 804 by the drainage system. The body fluid in 801 is drawn out, thereby achieving the effect of collecting the body fluid in the patient's body, avoiding the body fluid from hindering the surgical operation of medical staff; since the body fluid absorption system operates independently, when the body fluid is absorbed into the rotating tube 501 and the elastic tube 601, the adjustment operation of the camera probe 602 can be carried out, and it will not affect the medical staff to operate on the patient with a scalpel. While absorbing the fluid, the angle of the camera probe 602 is adjusted and the operation is performed, thereby reducing the operation time and improving the efficiency of the operation.

[0051] On the one hand, this solution can achieve the extension and contraction of the camera probe 602 and the elastic tube 601, achieve the multi-angle adjustment effect of the camera probe 602, and achieve the effect of the elastic tube 601 and the protective cover 603 on the expansion of the internal tissue; on the other hand, when body fluids block the view, the body fluids can be quickly absorbed to avoid the body fluids blocking the line of sight, which is convenient for photographing the lesion site, thereby reducing the shadow phenomenon in the captured image, facilitating medical staff to obtain information on the location of the lesion, facilitating medical staff to perform surgery on patients, improving the flexibility of the device, improving surgical accuracy, reducing surgical time and difficulty, improving the treatment effect on patients, and effectively reducing surgical risks.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
