Description

Technical Field

[0001] This utility model belongs to the field of dental auxiliary equipment technology, specifically relating to a multifunctional integrated protective sleeve. Background Technology

[0002] Root canal surgery is the most common and effective treatment for pulpitis and periapical periodontitis. Currently, the commonly used instruments for root canal treatment include root canal motors for enlarging and cleaning root canals and heated gutta-percha machines for heating gutta-percha and injecting it into the root canal. However, there are some problems in using these pen-gun instruments.

[0003] For example, when using a heated gutta-percha machine, it is usually placed on a shelf on the workbench with the working needles exposed. Medical staff can easily touch the working needles when picking up or putting away items on the workbench. At the same time, the heated gutta-percha machine will come into contact with the patient's mouth, saliva, and blood during use. Therefore, according to hospital requirements, it must be used by one person and disinfected after each use. The traditional disinfection method is to wrap it with protective paper and then use scissors to trim off the excess. This is time-consuming, and the protective paper is very sticky. It takes a long time to tear off the protective paper covering the surface of the heated gutta-percha machine. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multifunctional integrated protective sleeve that is simple in structure, easy to operate, and suitable for pen gun instruments such as hot gutta-percha machines and root canal motors of different specifications.

[0005] The present invention adopts the following technical solution:

[0006] A multifunctional integrated protective sleeve is detachably mounted on a pen-gun-type instrument. The pen-gun-type instrument includes a handheld body and a working needle located on the top of the handheld body. The sleeve is characterized by comprising a needle tip protective sleeve and a body receiving sleeve. The needle tip protective sleeve is mounted on the body and includes a fixing ring detachably mounted on the upper part of the handheld body, a silicone protective cover located on the top of the fixing ring and surrounding the working needle, and a push sleeve located on the upper end of the silicone protective cover, capable of moving the silicone protective cover downwards and flipping it over to fit over the upper part of the handheld body. The top of the silicone protective cover is open. The body receiving sleeve is located at the bottom of the fixing ring and is in a rolled-up state. When the fixing ring is mounted on the upper part of the handheld body, the body receiving sleeve can unfold downwards and fit against the outside of the handheld body.

[0007] Furthermore, the push sleeve includes a push portion extending upward from the top of the silicone protective cover vertically, and a silicone limiting eave disposed inside the push portion, through which the handheld body and the working needle can pass.

[0008] Furthermore, a protective cavity for accommodating the working needle is formed between the silicone limiting eave and the silicone protective cover.

[0009] Furthermore, the cross-section of the silicone protective cover is a conical structure that is larger at the top and smaller at the bottom.

[0010] Furthermore, the diameter of the fixing ring is smaller than the diameter of the pushing sleeve.

[0011] Furthermore, the fixing ring includes a silicone ring that can be fitted onto the outer periphery of the machine body, a plurality of positioning parts spaced apart on the outer periphery of the silicone ring, and a cable tie that can pass through the plurality of positioning parts to fix the silicone ring to the outer periphery of the machine body.

[0012] Furthermore, the body housing sleeve and the needle protective sleeve are integrally formed.

[0013] Furthermore, the housing sleeve is made of a semi-transparent rubber material.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, through the mutual cooperation between the needle protective sleeve set on the body and the body receiving sleeve set at the bottom of the fixing ring, and defining the specific structure of the needle protective sleeve, can quickly wrap around the handheld device body, preventing the handheld device body from being contaminated with the patient's saliva and blood, thus achieving the function of preventing contamination and cross-infection of the handheld device body. It can also arbitrarily switch the position between the silicone protective cover and the working needle, preventing the working needle from being constantly exposed to the outside, preventing medical personnel from being pricked by the working needle, achieving the function of preventing sharps injuries, and improving the safety of pen-gun-type instruments. Furthermore, the needle protective sleeve has a simple structure and is easy to operate. This saves medical staff's operation time. When using the device, first install the fixing ring at a suitable position on the upper part of the handheld unit, ensuring the working needle is protected within the silicone protective cover. Then, unfold the retracted housing sleeve downwards, allowing it to wrap around and cover the outer circumference of the device. When the working needle needs to be used, the medical staff moves the push sleeve downwards, causing the upper end of the silicone protective cover to move downwards, flipping the cover over and placing it on the upper part of the handheld unit. At this point, the working needle is exposed above the push sleeve. After using the working needle, the medical staff moves the push sleeve upwards, causing the upper end of the silicone protective cover to move upwards, returning the cover to its initial position. The working needle is now located inside the silicone protective cover.

[0015] By cooperating with the silicone ring fitted around the outer periphery of the device, multiple positioning parts spaced apart around the silicone ring, and cable ties that can pass through the multiple positioning parts, the fixing ring can be positioned at a suitable location on the pen gun instrument. This allows it to adapt to different models of heated gutta-percha machines or root canal motors. It can also protect the handheld body of the root canal motor and heated gutta-percha machine and prevent the working needles on the root canal motor and heated gutta-percha machine from being exposed to the outside, thus preventing medical staff from being pricked or burned by the working needles on the root canal motor and heated gutta-percha machine. This improves the adaptability of the multi-functional integrated protective sleeve. Attached Figure Description

[0022] The present invention will be further described below through specific embodiments.

[0023] like Figures 1 to 5 As shown, this embodiment provides a multi-functional integrated protective sleeve, including a needle protective sleeve 1 and a body receiving sleeve 2; wherein, the multi-functional integrated protective sleeve can be detachably installed on a pen gun-type instrument, the pen gun-type instrument including a handheld body and a working needle disposed on the top of the handheld body.

[0024] A needle protective sleeve 1, mounted on the machine body 31, includes a detachable fixing ring 11 mounted on the upper part of the machine body 31, a silicone protective cover 12 mounted on the top of the fixing ring 11 and surrounding the outer periphery of the working needle 32, and a push sleeve 13 mounted on the upper end of the silicone protective cover 12 and capable of moving the silicone protective cover 12 downwards and flipping it over to fit over the upper part of the machine body 31. The top of the silicone protective cover 12 is open. By setting the fixing ring 11, silicone protective cover 12, and push sleeve 13, when the fixing ring 11 is mounted on the upper part of the machine body 31, medical personnel can use the push sleeve 13 to move the silicone protective cover 12 downwards or upwards, so that the silicone protective cover 12 surrounds the outer periphery of the working needle 32 or fits over the outer periphery of the machine body 31. To prevent the working needle 32 from being constantly exposed, thus preventing medical staff from being pricked by the working needle 32 and achieving the function of preventing sharp object injuries, the safety of using the pen-gun type instrument 3 is improved; moreover, the needle protection sleeve 1 has a simple structure, is easy to operate, and saves medical staff's operation time; specifically, the push sleeve 13 includes a push part 14 that is vertically set at the top of the silicone protective cover 12 and extends upward, and a silicone limiting eave 15 set inside the push part 14 for the hand to hold the body 31 and the working needle 32 to pass through; furthermore, a protective cavity 16 for accommodating the working needle 32 is formed between the silicone limiting eave 15 and the silicone protective cover 12; when the push sleeve 13 moves the silicone protective cover 12 downward, the silicone protective cover 12 is fitted around the outer periphery of the body 31. The inner circumference of the silicone limiting eaves 15 is pressed and fixed against the outer circumference of the body 31; further, the silicone protective cover 12 is made of silicone material, and its cross-section is a conical structure with a larger top and a smaller bottom; wherein, the diameter of the fixing ring 11 is smaller than the diameter of the pushing sleeve 13; further, the fixing ring 11 includes a silicone ring 17 that can be fitted onto the outer circumference of the body 31, a plurality of positioning parts 18 spaced apart on the outer circumference of the silicone ring 17, and a cable tie 19 that can pass through the plurality of positioning parts 18 to fix the silicone ring 17 to the outer circumference of the body 31; by setting the silicone ring 17, the plurality of positioning parts 18 and the cable tie 19, the fixing ring 11 can be positioned in a suitable position on the pen gun instrument, thereby adapting to different models of hot gutta-percha machines or root canal motors, and can The handheld body 31 is used to protect the root canal motor and the heated gutta-percha machine, and to prevent the working needles 32 on the root canal motor and the heated gutta-percha machine from being exposed to the outside, thus preventing medical staff from being pricked or burned by the working needles 32 on the root canal motor and the heated gutta-percha machine. This improves the adaptability of the multi-functional integrated protective cover. Furthermore, the cable tie 19 is a disposable cable tie with a self-locking function in the prior art. Its specific structure and principle will not be described further here. Furthermore, the pushing part 14 is made of heat-resistant plastic material, and the silicone protective cover 12, silicone limiting edge 15, and silicone ring 17 are all made of high-temperature resistant silicone material, so that this utility model has a high-temperature resistance function and can be used for heated gutta-percha machines.

[0025] The device housing 2 is located at the bottom of the fixing ring 11 and is in a rolled-up state. When the fixing ring 11 is installed on the upper part of the handheld device 31, the device housing 2 can be unfolded downwards and fit against the outside of the handheld device 31, which can prevent the handheld device 31 from being contaminated with the patient's saliva and blood. Specifically, the device housing 2 is integrally formed with the needle protection sleeve 1 and can be set as a disposable item, which can be discarded after use without cleaning, reducing the workload of medical staff. Furthermore, the device housing 2 is made of high temperature resistant semi-transparent rubber material, which can cover and fit against the outer surface of different models of pen gun instruments 3 without affecting the medical staff's observation of the display screen 34 and touch control buttons 33 on the pen gun instrument 3.

[0026] Taking a heated gutta-percha machine as an example, the working process of installing a multi-functional integrated protective sleeve on the heated gutta-percha machine further illustrates the principle of this application. The working principle of this application is as follows:

[0027] When using the hot gutta-percha machine, first install the needle protector 1 at a suitable position on the upper part of the handheld body 31 of the hot gutta-percha machine via the fixing ring 11, so that the working needle 32 is located in the protective cavity 16 formed between the silicone protective cover 12 and the silicone limiting edge 15. Then, unfold the body receiving sleeve 2 from its rolled-up state downwards so that the body receiving sleeve 2 wraps around and covers the outer periphery of the handheld body 31. When the working needle 32 is needed, the medical staff pushes the sleeve 13 to move the upper end of the silicone protective cover 12 downwards and flip it over to cover the upper outer periphery of the handheld body 31, so that the working needle 32 passes through the top of the silicone protective cover 12 and is exposed above the pushing sleeve 13. When the silicone limiting edge 15 passes the working needle 32, the silicone protective cover 12 may undergo slight deformation, so that the needle tip of the working needle 32 passes through the opening of the silicone protective cover 12. When the hot gutta-percha machine is inserted into the patient's mouth, it does not come into contact with the silicone limiting edge 15. In rare cases, when dealing with very large root bones, the heating temperature needs to be increased to 200℃-230℃ before injection. During the heating process, the heating element generates high temperature, and the heat is conducted through heat conduction, causing the upper part of the handheld body 31 of the hot gutta-percha machine to become very hot. At this time, the silicone protective cover 12 on the upper part of the handheld body 31 can temporarily form a heat insulation layer to prevent the upper part of the handheld body 31 from burning the patient's mucosa. After the working needle 32 is used up, the medical staff pushes the sleeve 13 to move the upper end of the silicone protective cover 12 upward, so that the silicone protective cover 12 and the pushing sleeve 13 return to the initial position. At this time, the working needle 32 is located in the protective cavity 16.

[0028] In summary, by utilizing the above-mentioned technical solution of this utility model, through the mutual cooperation between the needle protective sleeve 1 set on the body 31 and the body receiving sleeve 2 set at the bottom of the fixing ring 11, and by defining the specific structure of the needle protective sleeve 1, it not only achieves the functions of quickly wrapping the handheld body 31 and preventing contamination and cross-infection, but also allows for arbitrary switching of the position between the silicone protective cover 12 and the working needle 32, preventing the working needle 32 from being constantly exposed to the outside, thus achieving the function of preventing sharp object injuries and improving the safety of using the pen gun-type instrument 3; in addition, the needle protective sleeve 1 has a simple structure, is easy to operate, and saves medical staff's operation time; furthermore, through the silicone ring 17 sleeved on the outer periphery of the body 31, and the spaced around the silicone ring 17, The cooperation between multiple positioning parts 18 and the cable ties 19 that can pass through multiple positioning parts 18 allows the fixing ring 11 to be positioned at a suitable position on the pen gun instrument 3, thereby adapting to different models of heated gutta-percha machines or root canal motors. It can also be used to protect the handheld body 31 of the root canal motor and heated gutta-percha machine and to prevent the working needles 32 on the root canal motor and heated gutta-percha machine from being exposed to the outside, thus preventing medical staff from being punctured or burned by the working needles 32 on the root canal motor and heated gutta-percha machine. This improves the adaptability of the multi-functional integrated protective sleeve. In addition, the body housing sleeve 2 and the needle protection sleeve 1 are integrally molded and can be set as disposable items, which can be discarded after use without cleaning, reducing the workload of medical staff.

[0029] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
