Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically, to an intracavitary curing spraying system. Background Art

[0002] Most of the nozzles on the market at present are for expanding the spraying range so that the drug can cover the lesion area more comprehensively. With the progress of medicine, different types of drugs have been developed to adapt to different lesions. For example, the currently popular hydrogel products can be used for hemostasis, repair and treatment of wounds. When used intracavitary, a better spraying effect can be obtained by spraying. However, the solution of such products is relatively viscous. When using the above-mentioned ordinary spraying tube, if the spraying angle of the sprayed liquid medicine is not enough, or the spraying is not uniform, the dispersion effect is also not good, and the liquid medicine is easy to accumulate at one point and cannot be sprayed in a large range, so multiple sprays are required.

[0003] One end of most nozzles is connected to a syringe, and the other end injects the liquid medicine. After endoscopic surgery, hemostatic drugs can be sprayed on the wound site for hemostasis. In the existing technology, most spraying tubes can only perform spraying work alone. When the liquid medicine needs ultraviolet-assisted irradiation, additional instruments are required for assistance. In addition, the irradiation area of the auxiliary instrument needs to be adjusted to overlap with the spraying area, which is not convenient for surgical operation and prolongs the operation time.

Detailed implementation manners

[0032] The technical content of the present utility model will be further described below in conjunction with embodiments: The following embodiments are illustrative and not restrictive, and the protection scope of the present utility model cannot be limited by the following embodiments.

[0033] First of all, it should be noted that Figure 1 and Figure 2 Figure 1 shows a schematic structural diagram of the nozzle 1 in the intracavitary curing spraying system. On the right side of the nozzle 1 is a part of the optical fiber cavity 21, which is the position where the emission light source performs photocuring. The optical fiber cavity 21 is separated from other components of the nozzle 1 and can work independently or simultaneously.

[0034] As Figures 1-10 shown, this embodiment provides an intracavitary curing spraying system, which is composed of a nozzle 1, a multi-cavity tube 2, a housing 3, a portable light source 4 and a connector 5. One end of the multi-cavity tube 2 is connected to the nozzle 1, and the other end is connected to the connector 5. The nozzle 1 is composed of a spraying shell 11 and a spraying core 12, and the upper end of the spraying core 12 is also provided with an inclined nozzle 111; the multi-cavity tube 2 is composed of an optical fiber cavity 21, a drug delivery cavity 22 and small holes 23 on the outer wall of the optical fiber cavity. The first end of the drug delivery cavity 22 abuts against the spraying core 12, and the second end abuts against the connector 5; the housing 3 is in a "y" shape. One side internally wraps the optical fiber assembly 6 and is connected to the portable light source 4 to provide the light source 42. The other side wraps a part of the multi-cavity tube 2 to a part of the connector 5. The connector 5 is set to be able to connect an injection device to transmit the liquid medicine. The housing 3 is composed of a symmetric left housing and a right housing, which is convenient for installation. The light source switch 41 of the portable light source 4 is used to control the light source 42, and the battery 43 provides electrical energy and can be replaced at any time. Moreover, the portable light source 4 is detachable, and portable light sources 4 with different specifications can be installed according to needs. The housing 3 and the portable light source 4 are connected by a spiral or snap-fastening method. Thus, a surgery related to gel curing can be performed in the cavity, and the light source switch 41 can be turned on while spraying the liquid medicine for ultraviolet curing, which saves the surgery time and is easy to operate.

[0035] Specifically, the nozzle 111 is provided with a single-hole and multi-hole structure according to needs. The spraying angle of the single-hole or multi-hole structure nozzle 111 can be 120°-150°, which can ensure spraying in a large range; and the spraying core 12 is set to be a spiral structure, which can be a double-spiral, triple-spiral or quadruple-spiral structure. When spraying a liquid medicine with a relatively high viscosity is required, it is difficult for a general spraying device to spray out or spray out a uniform liquid medicine. However, for the spiral-structured spraying core 12, the liquid medicine can rotate to generate centrifugal force after entering the spraying core 12, and can easily spray out the liquid medicine evenly from the nozzle 111, ensuring a good spraying effect. When a relatively thick liquid medicine or solution is needed, it can also be sprayed out more easily, and a liquid medicine or solution with a viscosity of 2.98 mPa·s to 40 mPa·s can be used in combination, which broadens the application range.

[0036] Specifically, the multi-chamber tube 2 of the in-vivo curing spraying system of the present utility model is used to transmit light and liquid medicine. It consists of an optical fiber chamber 21, a medicine delivery chamber 22, and small holes 23 on the outer wall of the optical fiber chamber. The multi-chamber tube 2 can be composed of one optical fiber chamber 21 and one medicine delivery chamber 22, or can be composed of multiple optical fiber chambers 21 and one medicine delivery chamber 22. Inside the optical fiber chamber 21 is an optical fiber 61, and the optical fiber core 611 of the optical fiber 61 can be set as single or multiple, which is used to transmit the light source 42 generated by the portable light source 4. The optical fiber chamber 21 is also provided with small holes 23 on the outer wall of the optical fiber chamber, so that the optical fiber 61 penetrates into the multi-chamber tube 2 at the small holes 23 on the outer wall of the optical fiber chamber and enters the optical fiber chamber 21. One end of the optical fiber chamber 21 located at the nozzle 1 is flush with the nozzle 111, so that the optical fiber 61 finally reaches the position flush with the nozzle 111 of the nozzle 1 to emit light for photocuring. The multi-chamber tube 2 and the connector 5 are inserted together as an integral component. The medicine delivery chamber 22 in the multi-chamber tube 2 transmits the liquid medicine. The liquid medicine enters through the connector 5 at the front end, passes through the medicine delivery chamber 22 to reach the spray core 12 with a spiral structure, and then is sprayed out from the nozzle 111 after passing through the spray core 12, and can be sprayed onto the wound surface for spraying. The optical fiber chamber 21 and the medicine delivery chamber 22 are both in the multi-chamber tube 2 but are separated, and the two can work simultaneously.

[0037] In some specific embodiments, when one medicine delivery chamber 22 and multiple optical fiber chambers 21 are provided in the multi-chamber tube 2, the optical fiber chambers 21 are evenly distributed around the medicine delivery chamber 22 with the medicine delivery chamber 22 as the center. The outer diameter of the multi-chamber tube 2 is set to 2.8 mm, the diameter of the medicine delivery chamber 22 is set to 1.4 mm - 1.6 mm, and the diameter of the optical fiber 61 is set to 0.2 mm - 0.3 mm.

[0038] Specifically, such as Figures 6-10As shown in the figure, the outer shell 3 in the intracavitary curing spraying system of the present utility model is composed of symmetrical left and right outer shells, which can be connected by means of glue bonding, threads or snap connections. After connection, it is clamped with the connector 5 at the front end for fixation. One side of it wraps the optical fiber assembly 6 and part of the multi-cavity tube 2. The optical fiber assembly 6 consists of an optical fiber 61, an optical fiber terminal 62 and an optical cone 7. The ultraviolet light required for curing is transmitted by the optical fiber 61. One end of the optical fiber 61 penetrates into the optical fiber cavity 21 in the multi-cavity tube 2 through the small hole 23 on the outer wall of the optical fiber cavity, and the other end is inserted into the optical fiber terminal 62. The end faces of the optical fiber terminal 62 and the optical fiber 61 are polished flush to facilitate connection with the optical cone 7 to receive the light source 42. The optical fiber terminal 62 is fixedly connected to the optical cone housing 71 of the optical cone 7 by interference fit. The optical cone 7 is composed of an optical cone housing 71 and an optical cone core 72, and processes the light source 42 from the portable light source 4. The optical cone core 72 is arranged inside the optical cone housing 71. The optical cone 7 couples the light emitted from the portable light source 4 into the optical fiber 61. The optical fiber 61 transmits the light source 42, and then reaches the nozzle 1 through the optical fiber cavity 21 in the multi-cavity tube 2 to emit light for photocuring. In some specific embodiments, the part of the optical fiber cavity 21 located at the nozzle 1 is arranged to be wrapped in the spraying shell 11 so as to fix the optical fiber 61 to transmit light smoothly.

[0039] As Figure 10 shown, as a reference for describing a specific usage method, when encountering in-vivo wound repair in clinical practice, a photosensitive curing gel product needs to be used. The liquid medicine is sprayed and cured at the wound for adhesion or repair. The intracavitary curing spraying system provided by the present utility model can spray the liquid medicine and perform photocuring at the same time. The medical staff holds one end of the outer shell 3 and the portable light source 4. The prepared liquid medicine needs to be stored in an injection device in advance. The injection device can be any syringe or injection pump that can be connected to the connector 5. The injection device is connected to the connector 5, and the entry of the liquid medicine is controlled by the switch on the injection device. The liquid medicine will pass through the medicine delivery cavity 22 in the multi-cavity tube 2 and then reach the spray core 12 in the nozzle 1. The spiral structure of the spray core 12 makes the liquid medicine rotate to generate centrifugal force, and finally it is evenly sprayed out through the nozzle 111. And because the nozzle 111 has a spraying angle of 150°, a large range can be covered during spraying, and there is no need to worry about incomplete spraying. When spraying the liquid medicine, photocuring is also carried out at the same time. A portable light source 4 with a suitable specification is installed in advance. The light source switch 41 located at the front end of the portable light source 4 can be clearly seen at the end close to the medical staff. After pressing the light source switch 41, the light enters the optical cone core 72 of the optical cone 7 for coupling. The coupled light is transmitted by the optical fiber 61. The optical fiber 61 enters the optical fiber cavity 21 of the multi-cavity tube 2 through the small hole 23 on the outer wall of the optical fiber cavity, and then reaches the nozzle 1 to perform photocuring. While pressing the light source switch 4, the injection device is opened to inject the liquid medicine. Aligning the nozzle 1 with the wound surface can perform the spraying of the liquid medicine and the photocuring of the liquid medicine. The spraying is evenly dispersed and has a large range, the liquid medicine is cured in time, which greatly saves the operation time, and the device is simple and the operation is convenient.

It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative labor.
