Description

Technical Field

[0001] The utility model relates to the technical field of medical surgical instruments, in particular to a device used for water jet surgery, which can be suitable for medical surgery on soft tissues and hard tissues. Background Art

[0002] With the advancement of medical science, large and small surgeries have become routine treatment methods for doctors. Surgery can replace the original drug treatment and fundamentally solve the patient's disease. With the improvement of surgical technology, the subsequent impact of surgery is getting smaller and smaller, and it has gradually become a mainstream treatment method. Current medical surgeries mainly include medical surgeries for soft tissues and medical surgeries for hard tissues. Among them:

[0003] Soft tissue usually refers to human skin, blood vessels, muscles and other tissues. Existing soft tissue surgeries usually involve loosening or lengthening soft tissues such as skin and tendons. Currently, they are mostly performed using physical cutting methods and instruments (surgical knives), which cause significant tissue damage and have a certain impact on the patient's subsequent recovery time and rehabilitation effect.

[0004] Hard tissue usually refers to human bone tissue. Existing hard tissue surgeries are usually aimed at diseases such as bone tissue injury and poor fracture healing, which are common and difficult clinical diseases. At present, such diseases often require mechanical cleaning of hardened bones and avascular tissue until tissue with good blood supply is exposed. A lot of tissue needs to be removed, and physical cutting (surgical knives) is often required, which causes greater trauma, poor postoperative healing, and unsatisfactory efficacy.

[0005] Therefore, there is an urgent need in this field to design a surgical medical device that is suitable for both soft tissue surgery and hard tissue surgery, mainly to overcome the defects brought about by the above-mentioned existing physical cutting (surgical knife) operation method. There is also a need for a surgical medical device with a positioning function that can locate the lesion during the operation to facilitate the implementation of precise surgery. Utility Model Content

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model can be applied to medical surgeries on soft tissues and hard tissues. There is no need to use a knife to perform physical cutting on the lesion, which reduces the damage and trauma to the tissue. The postoperative recovery effect is good, and the surgery is convenient while improving the effect and efficiency of the treatment.

[0018] 2. The utility model also designs a positioning structure that is beneficial to improving surgical accuracy and improving the quality of surgery. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model discloses a device for water jet surgery. Figure 1 As shown: it includes a water source 1, a pressurizing device 2, a switch 3, and a hand-held operating part 4 with a water jet nozzle; the water source 1 is connected to the hand-held operating part 4 with a water jet nozzle through a pipeline, and the pressurizing device 2 is arranged on the pipeline. The switch 3 is used to control the water supply to the hand-held operating part 4 with the water jet nozzle; a visible light locator 5 is also arranged at the nozzle of the hand-held operating part 4, and the light emitting direction of the visible light locator 5 is consistent with the water flow injection direction of the nozzle.

[0022] When the utility model is used, the switch 3 controls the jet water to be pressurized from the water source 1 through the pressurizing device 2 and then delivered to the hand-held operating part 4, and then ejected through the water jet nozzle to perform soft tissue and hard tissue surgery. The visible light locator 5 assists the doctor in locating the lesion site through the visible light it emits, which is conducive to the implementation of precise surgery.

[0023] When the device is used in soft tissue surgery, such as when a tendon is damaged or torn, a defect is created in the middle due to contraction and cannot be sutured. The device can be used to punch out multiple microholes at the tendon position without the need to physically cut the tissue with a surgical knife. The original tissue can be stretched to reduce damage to the tissue itself, and the postoperative healing effect is good. It facilitates surgery while improving the effectiveness and efficiency of treatment.

[0024] When the device is used for hard tissue surgery, such as bone tissue surgery, there is no need to physically cut the tissue with a surgical knife, which reduces damage to the tissue itself, and has a good postoperative recovery effect, making surgery easier while improving the effect and efficiency of treatment. At the same time, it can also stimulate the original tissue to provide sufficient blood supply, making the surgical effect better.

[0025] As an implementation method, the visible light locator 5 is a small laser head. For example, a 3-9V industrial red light small dot positioning light laser head (single or cross diode module 650nm / 5mw) from a super-resistant laser factory is used, and the outer dimensions of the laser head are 6.5mmx18mm. Or a 650nm / 5mw red light dot laser dot module adjustable focus laser positioning light from Shenzhen Xinkunyang Technology is used, and the outer dimensions of the laser head are 16mmx25mm.

[0026] In the present invention, the switch 3 can be arranged on the hand-held operating part 4. When the water source needs to be connected, the switch button on the hand-held operating part 4 can be directly activated.

[0027] In the present invention, the switch 3 can also be designed as a foot pedal. Considering that the hand-held operating part 4 needs to perform other operations during the operation and the operating space is limited, the foot pedal is used as an external switch to control the delivery of the jet water to the nozzle.

[0028] In the present invention, a suction tube 6 is also provided beside the nozzle of the hand-held operating part 4, and the suction tube 6 is connected to the negative pressure generator through a negative pressure tube 7. The suction tube 6 is used to suck out excess liquid during surgery.

[0029] In the present invention, the visible light locator 5 can be equipped with a micro power supply. Alternatively, the power supply of the visible light locator 5 is arranged in the hand-held operating part 4 , and the power supply is electrically connected to the visible light locator 5 .

[0030] In the present invention, the pressurizing device 2 is a water pump.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
