Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an installation fixture for a medical device handle and a medical device handle housing assembly. Background Technology

[0002] Many surgical device manufacturers have developed medical devices with cutting and suturing functions. These devices mainly include reusable handles, adapters, and end effectors. However, the reusable electric handle core typically requires steam sterilization after each use before reuse in surgery. Current sterilization methods for handles involve steam sterilization. Repeated steam sterilization can lead to moisture buildup inside the handle, potentially causing short circuits and damage to the handle core's circuitry. Furthermore, the handles are expensive, and discarding them after a single use significantly increases surgical costs for patients. The inventors of this invention envision creating a disposable sterile shell to encapsulate a sterile handle core. This sterile handle core can be reused without requiring high-temperature sterilization. However, this introduces the problem of bacteria from the handle core falling onto the surgical nurse's arm during the sterile shell encapsulation process. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an installation fixture for the handle of a medical device and a medical device handle housing assembly that can prevent bacteria on the handle core from falling onto the arm of the surgical nurse during the aseptic housing encapsulation process.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0007] In a first aspect, embodiments of the present invention provide an installation fixture for a handle of a medical device, the installation fixture comprising: a hand-held portion, a shielding portion, and a handle-receiving portion connected to the hand-held portion;

[0008] The handle receiving portion is recessed towards the hand-held portion to form a concave space for placing the sterile outer shell of the handle;

[0009] The shielding portion is connected to the handheld portion and / or the handle receiving portion, and protrudes laterally from the handheld portion and the handle receiving portion.

[0010] Optionally, the handle receiving portion is provided with a cover mounting portion for the cover of the sterile shell to enter the recessed space and connect with the body of the sterile shell.

[0011] Optionally, the cover mounting portion is a cover mounting hole provided on the side wall of the handle receiving portion. When the body is located in the recessed space, the cover mounting hole corresponds to the insertion port on the side wall of the body for the cover to be inserted.

[0012] Optionally, the cover mounting part is an outwardly expanding structure located at the opening of the concave space, allowing the cover to enter the concave space and connect with the body.

[0013] Optionally, the shielding part can switch between an open state and a folded state. When the shielding part is in the open state, the shielding part protrudes laterally from the handheld part and the handle receiving part.

[0014] Optionally, the shielding part is an umbrella-shaped folding structure.

[0015] Optionally, the installation fixture may further include a pushing component for installing the cover.

[0016] Secondly, embodiments of the present invention provide a medical device handle housing assembly, including the aforementioned mounting fixture and a sterile housing for the medical device handle;

[0017] The sterile shell includes a body and a cover. The body has a first cavity for placing the handle core inside, and the body has a first opening that communicates with the first cavity and allows the handle core to enter and exit the first cavity. The cover is used to selectively cover the first opening on the body.

[0018] The sterile outer shell can be selectively placed into the recessed space.

[0019] Optionally, the inner wall of the body is provided with a slot at the first opening, and the side wall of the body is provided with an insertion port communicating with the slot;

[0020] The side wall of the handle receiving part is provided with a cover mounting hole. When the sterile shell is placed in the recessed space, the cover mounting hole corresponds to the insertion port, and the cover can be inserted into the slot in sequence through the cover mounting hole and the insertion port.

[0021] (III) Beneficial Effects

[0022] The beneficial effects of the present invention are as follows: The installation fixture for the handle of the medical device of the present invention, by employing a hand-held part, a handle receiving part, and a shielding part, with the shielding part connected to the hand-held part or the handle receiving part and protruding laterally from the hand-held part and the handle receiving part, can separate the sterile handle core from the arm of the nurse holding the sterile installation fixture, thus preventing bacteria from falling onto the surgical nurse's arm and contaminating the surgical nurse's arm during the sealing of the handle core.

[0023] The medical device handle housing assembly of the present invention uses a sterile body and cover to encapsulate the unsterilized handle core. Compared with the prior art, the handle core does not need to be sterilized by high-temperature boiling, thus avoiding the situation where repeated sterilization of the handle core will cause the inside of the handle core to become damp and damaged. At the same time, the handle core is encapsulated in a sterile housing and can be reused, thus achieving the technical effect of reducing costs. Attached Figure Description

Detailed Implementation

[0043] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Example 1:

[0045] Reference Figure 1 , Figure 2 and Figure 10 This invention provides a medical device handle housing assembly and a handle core 4 that cooperates with it. The medical device handle housing assembly includes an installation fixture and a sterile housing for encapsulating the handle core 4. The sterile housing and the handle core 4 together constitute the handle 1 of the medical device. The sterile housing includes a body 2 and a cover 3.

[0046] The main body 2 has a first cavity 25 for placing the handle core 4, and the main body 2 has a first opening communicating with the first cavity 25. The first opening is used for the handle core 4 to enter and exit the first cavity 25, that is, when the handle core 4 is sealed, the handle core 4 is placed into the first cavity 25 through the first opening. The cover 3 is used to selectively cover the first opening on the main body 2.

[0047] Furthermore, the inner wall of the main body 2 is provided with a slot 5 at the first opening, and the side wall of the main body 2 is provided with an insertion port 17 communicating with the slot 5. The cover 3 can be inserted into the slot 5 through the insertion port 17, thereby sealing the first cavity 25.

[0048] The main body 2 and the cover 3 are sterile, and the handle core 4 can be sealed inside the first cavity 25 to prevent bacteria on the handle core 4 from leaking to the outer surface of the sterile shell. Before use, the handle core 4 is separated from the sterile shell. The sterile shell is sterilized separately, while the handle core 4 does not need to be sterilized. During use, the handle core 4 is placed inside the sterile shell. In this way, the entire handle 1 can be reused, reducing the cost of use. It also avoids the situation where the handle core 4 becomes damp and damaged due to repeated sterilization of the entire handle 1, and reduces the manpower, material and resource consumption of hospitals due to sterilization.

[0049] Furthermore, the handle core 4 houses a motor and control circuit. A first control element 7, electrically connected to the control circuit, is located on the outer side of the handle core 4. A second control element 8 is positioned on the main body 2 at the location corresponding to the first control element 7 when the handle core 4 is placed inside the sterile outer shell. The second control element 8 is linked to the first control element 7; that is, when the second control element 8 is triggered, the first control element 7 is also triggered. In this embodiment, the first control element 7 and the second control element 8 are buttons; when the second control element 8 is pressed, it activates the first control element 7. Of course, the invention is not limited to this; the first control element 7 and the second control element 8 can also be commonly used switches such as sensors.

[0050] In addition, the handle core 4 is equipped with a vibration motor. When the doctor triggers the second control component 8, the vibration motor provides vibration feedback to remind the doctor that a work instruction has been received; or it provides tactile feedback when a certain surgical procedure is completed; or it provides a fault alarm reminder.

[0051] Reference Figure 8 and Figure 9 The main body 2 also has a second cavity 26 for inserting an adapter, and the side wall of the main body 2 has a second opening communicating with the second cavity 26, which is used for the adapter to enter and exit the second cavity 26. The second cavity 26 is separated from the first cavity 25 by a partition.

[0052] Furthermore, the motor spindle 6 extends to the outside of the handle core 4. A first through hole is provided in the partition inside the body 2 corresponding to the position of the motor spindle 6. An output shaft 22 is installed inside the first through hole. When the handle core 4 is encapsulated in a sterile shell, the motor spindle 6 is precisely inserted into one end of the output shaft 22, and the other end of the output shaft 22 can be connected to the shaft in the adapter inserted into the second cavity 26. Because the motor spindle 6 carries bacteria, the outer end of the motor spindle 6 does not protrude through the first through hole, but instead transmits power to the adapter through the output shaft 22.

[0053] The handle core 4 is also provided with a first connector 23 that is electrically connected to the circuit board. A second through hole is provided on the partition corresponding to the position of the first connector 23, and a second connector 24 is disposed within this second through hole. When the handle core 4 is encapsulated in a sterile shell, the first connector 23 contacts the second connector 24, allowing the second connector 24 to be electrically connected to the adapter. Preferably, the first connector 23 is a female pin, and the second connector 24 is a male pin. However, the invention is not limited to this; the first connector 23 and the second connector 24 can also be other commonly used electrical connection components.

[0054] Furthermore, the partition comprises three plastic layers, with the middle layer being a perforated reinforcing rib. The reinforcing rib is designed to reduce the wall thickness of the partition, ensuring uniform wall thickness across all parts and preventing injection defects during the injection molding process. The reinforcing rib also enhances the strength of the partition while reducing material usage and lowering costs.

[0055] Combination Figure 7 As shown, two limiting holes 21 are provided on the two opposite side walls of the second cavity 26. The limiting holes 21 cooperate with the buckle of the fixed adapter to achieve the locking function, thereby installing the handle 1 and the adapter together.

[0056] A display screen 9, electrically connected to the control circuit, is embedded on the side of the handle core 4 to display the operating parameters of the handle core 4, thus improving human-computer interaction. In this embodiment, the first opening is located at the bottom of the body 2, and the cover 3 is the bottom cover of the body 2. The side wall of the body 2, corresponding to the position of the display screen 9, is made of transparent material. Of course, the first opening of the body 2 can also be located on the side wall of the body 2, with the cover 3 correspondingly located on the side wall of the body 2.

[0057] In existing designs, the controller core 4 and battery are separate components. When the battery is installed in the controller core 4, there is a continuous power consumption issue, and the battery cannot be recharged, resulting in a short battery life for the controller core 4. This embodiment integrates the controller core 4 and battery, with the battery housed within the controller core 4 and equipped with a dedicated charger for recharging. Furthermore, the cover 3 has a trigger component. When the cover 3 is installed in the slot 5, the trigger component forms a trigger connection with the controller core 4, triggering the battery within the controller core 4 to supply power. When the cover 3 is installed in the slot 5, the control circuit within the controller core 4 is open, and the battery does not supply power. Specifically, the trigger component is a magnet, and the battery power switch within the controller core 4 is a reed switch.

[0058] In this embodiment, the handle uses a sterile body 2 and a cover 3 to encapsulate the unsterilized handle core 4. Compared with the prior art, the handle core 4 does not need to be sterilized by high-temperature steaming, which avoids the situation where the handle core 4 will be damaged by moisture due to repeated sterilization. At the same time, the handle core 4 is encapsulated in a sterile shell and can be reused, thus achieving the effect of reducing costs.

[0059] Reference Figure 1 When the contaminated handle core 4 is inserted into the first cavity 25 from above the body 2, bacteria on the handle core 4 may fall onto the outer surface of the body 2 and onto the nurse's arm. To solve the above-mentioned technical problem, this embodiment also provides an installation fixture for the handle, as shown in the figure. Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The installation fixture 10 includes: a hand-held part 11, a shielding part 12, and a handle receiving part 13 connected to the hand-held part 11.

[0060] The handle receiving portion 13 is recessed towards the hand-held portion 11 to form a concave space for placing the sterile outer shell of the handle 1.

[0061] The shielding portion 12 is connected to the handheld portion 11 and the handle receiving portion 13, and protrudes laterally from both to block bacteria from the handle core 4, preventing them from falling onto the nurse's arm. Because the sterile outer shell is placed in the recessed space, it can prevent bacteria from the contaminated handle core 4 from falling onto the outer surface of the sterile outer shell to a certain extent. The shielding portion 12, handheld portion 11, and handle receiving portion 13 can be integrally formed or detachably connected. For example, the shielding portion 12 and handheld portion 11 can be threaded, magnetically connected, or snap-fitted. Of course, in other embodiments of the invention, the shielding portion 12 can be selectively connected to either the handheld portion 11 or the handle receiving portion 13, but not both simultaneously.

[0062] Preferably, in order to completely prevent bacteria from the handle core from falling onto the outer surface of the sterile shell, the recessed space can cover the entire area of ​​the circumferential outer surface of the sterile shell. In this case, the handle receiving part 13 is provided with a cover mounting part for the cover 3 of the sterile shell to enter the recessed space and connect with the body 2 of the sterile shell.

[0063] In this embodiment, the cover mounting part is a cover mounting hole 14 provided on the side wall of the handle receiving part 13. When the body 2 is located in the concave space, the cover mounting hole 14 corresponds to the insertion port 17 on the side wall of the body 2 for the cover 3 to be inserted. The cover 3 can be inserted into the slot 5 in sequence through the cover mounting hole 14 and the insertion port 17, thereby sealing the first cavity 25.

[0064] Furthermore, in this embodiment, the side wall portion of the handle receiving portion 13 where the cover mounting hole 14 is located forms a laterally protruding boss relative to other side wall portions, and the outer end of the boss is a rectangular plane. The outer end of the cover mounting hole 14 is also on a plane, and the length of the cover mounting hole 14 is greater than the thickness of the aforementioned "other side walls" of the handle receiving portion 13, thus ensuring that the cover is more stable during installation.

[0065] It should be further explained that the installation fixture 10 is sterile. The nurse holding the installation fixture and the sterile outer shell does not touch the sterile handle core 4. The sterile handle core 4 is placed inside the sterile body 2 by another nurse.

[0066] This embodiment also provides a method for installing the handle core 4 and the sterile outer shell using the above-described mounting fixture, comprising the following steps:

[0067] S1. Place the sterile shell body 2 into the recessed space of the handle receiving part 13, with the cover mounting hole 14 on the handle receiving part 13 facing the insertion port 17 on the side wall of the body 2.

[0068] S2. Place the handle core 4 inside the first cavity 25 of the main body 2;

[0069] S3. Push the cover 3 into the socket 17 through the cover mounting hole 14, and then push it into the inside of the slot 5 through the socket 17. The sterile shell seals the handle core 4.

[0070] S4. Pour the sterile outer shell out of the mounting fixture 10 and onto the sterile tabletop.

[0071] The mounting fixture for the handle of the medical device in this embodiment uses a hand-held part 11, a handle receiving part 13, and a shielding part 12. The shielding part 12 is connected to the hand-held part 11 and / or the handle receiving part 13 and protrudes laterally from the hand-held part 11 and the handle receiving part 13. Compared with the prior art, it can separate the handle core 4 from the nurse's arm and avoid bacteria from scattering and contaminating the surgical environment when the handle core 4 is packaged.

[0072] Example 2:

[0073] Reference Figure 11 In this embodiment, the medical device handle housing assembly includes an installation fixture and a sterile housing for encapsulating the handle core 4. The sterile housing differs from that in Embodiment 1 in that it also includes a fixing device for detachably fixing the body 2 and the handle core 4 together.

[0074] Specifically, the fixing device includes a press-out component 15, which is located in the body 2 and installed on the side of the body 2 away from the first opening. In this embodiment, the press-out component 15 is a snap-fit, and the upper part of the handle core 4 is provided with a limiting groove 16 that cooperates with the press-out component 15.

[0075] When the handle core 4 is pressed for the first time, the buckle is inserted into the limiting groove 16, and after a slight pop-up, it remains in the inserted working state; when the handle core 4 is pressed for the second time, the buckle is disengaged from the limiting groove 16, releasing the restriction on the handle core 4, and the handle core 4 can be taken out in this way.

[0076] In this embodiment, the handle 1 uses a fixing device, which makes the connection between the body 2 and the handle core 4 more secure than in embodiment 1, preventing the handle core 4 from becoming loose.

[0077] Reference Figure 12 and Figure 13The difference between this installation fixture 10 and Embodiment 1 is that the shielding part 12 is an umbrella-shaped folding structure. This umbrella-shaped folding structure can switch between an open state and a folded state. When the umbrella-shaped folding structure is in the open state, it protrudes laterally from the handhold part 11 and the handle receiving part 13, which can shield bacteria that fall from the handle core 4. When the umbrella-shaped folding structure is in the folded state, it is folded and stored, and does not protrude laterally from the handhold part 11 and the handle receiving part 13, thereby making the installation fixture 10 smaller in size and easier to store and carry.

[0078] Furthermore, the umbrella-type folding structure includes an umbrella pole, a push seat, a support frame, a skeleton, and an umbrella canopy. The top end of the umbrella pole is connected to the handle receiving portion 13, and the bottom end of the umbrella pole is connected to the hand-held portion 11. A push seat is fitted onto the umbrella pole, and the push seat is hinged to one end of the support frame. The other end of the support frame is hinged to the middle of the skeleton, and the upper end of the skeleton is hinged to the top end of the umbrella pole. An umbrella canopy is installed on the skeleton to block bacteria.

[0079] Example 3:

[0080] See Figure 14 In this embodiment, the medical device handle housing assembly includes an installation fixture and a sterile housing for encapsulating the handle core 4. Unlike embodiment 1, the sterile housing has an anti-slip structure 18 on its upper surface of the cover 3. Specifically, the anti-slip structure 18 can be anti-slip textures, anti-slip particles, or grooves, used to increase the friction between the upper surface of the cover 3 and the fingers. Through the friction between the upper surface of the cover 3 and the fingers, the cover 3 can be pushed out of the slot 5, allowing the handle 1 to be removed.

[0081] Reference Figure 15 The difference between the installation fixture 10 and Embodiment 1 is that the installation fixture 10 also includes a pushing component 19 for installing the cover 3;

[0082] When the front end of the cover 3 enters the slot 5 and the rear end of the cover 3 is inserted into the cover mounting hole 14, the pushing component 19 can hold against the rear end of the cover 3 and push it completely into the slot 5 to complete the encapsulation of the core assembly 4.

[0083] Specifically, the pushing component 19 can be plate-shaped or rod-shaped, and its height or diameter is smaller than the height of the cover mounting hole 14. Since the mounting fixture includes the pushing component 19, the cover 3 in this embodiment is more convenient to install.

[0084] Example 4:

[0085] Reference Figure 16In this embodiment, the medical device handle housing assembly includes an installation fixture and a sterile housing for encapsulating the handle core 4. This sterile housing differs from that in Embodiment 1 in that the body 2 does not have slots 5 and insertion ports 17. In this embodiment, the cover 3 is a bottom cover and has a cavity to accommodate the bottom of the body 2 (the "upper" and "lower" of the sterile housing are indicated by...). Figure 7 (Referring to the state at that time), the cover 3 closes onto the first opening of the body 2, thereby sealing the first cavity 25. Specifically, the body 2 and the cover 3 are connected by threads, magnetic attraction, or snap-fit.

[0086] The installation fixture in this embodiment differs from that in Embodiment 1 in that the cover mounting portion on the handle receiving portion 13 is an outwardly expanding structure 20 located at the opening of the concave space, allowing the cover 3 to enter the concave space and connect with the body 2. The cover 3 can easily close onto the first opening of the body 2 through the outwardly expanding structure 20, thereby sealing the first cavity 25.

[0087] Example 5:

[0088] Reference Figure 17 In this embodiment, the handle core 4 used in the medical device handle housing assembly differs from that in Embodiment 1 in that the motor spindle 6 of the motor 27 inside the handle core 4 does not extend to the outside of the handle core 4.

[0089] In this embodiment, the housing of the handle core 4 is provided with a third through hole at the position corresponding to the motor spindle 6. The adapter shaft 28 is rotatably fixed on the housing of the handle core 4, and the axis of the adapter shaft 28 coincides with the rotation axis of the motor spindle 6.

[0090] The motor spindle 6 of motor 27 is connected to one end of the adapter shaft 28. The other end of the adapter shaft 28 extends from the third through hole to the outside of the handle core 4 and is connected to the inner end of the output shaft 22 (in this embodiment, the inner end of the output shaft 22 is the lower end). Specifically, the inner end of the adapter shaft 28 (i.e., the end used to engage with the motor spindle 6, in this embodiment, the inner end of the adapter shaft 28 is the lower end) is provided with a slot for axially movable and circumferentially limited insertion into the motor spindle 6 of motor 27. An insulating component 29 is provided at the connection position between the slot and the motor spindle 6 to prevent static electricity on the adapter shaft 28 from being conducted to the motor spindle 6.

[0091] Specifically, the insulating component 29 can be an insulating sleeve, an insulating layer wrapped around the outer circumference of the motor spindle 6, or an insulating layer covering the inner end of the adapter shaft 28 and the inner wall of the slot. It should be noted that the insulating component 29 can be made of electrically insulating materials such as resin, plastic, silicone rubber, or PVC.

[0092] In this embodiment, the handle core 4 of the handle 1 has a motor spindle 6 of the motor 27 connected to one end of the adapter shaft 28, with the other end of the adapter shaft 28 extending to the outside of the handle core 4. An insulating component is provided between the motor spindle 6 and the adapter shaft 28 to prevent external static electricity from being conducted to the motor spindle 6 through the adapter shaft 28. This avoids external static electricity from affecting the motor 27 and circuit board inside the handle 1, thereby extending the service life of the handle core 4.
