Description

RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/400,476, filed on Jan. 6, 2017, allowed; which claims the priority of provisional patent application Ser. No. 62/276,007, filed on Jan. 7, 2016; the entireties of which are incorporated herein by reference.

FIELD

This disclosure relates generally to a handheld surgical device configured for performing one or more surgical procedure(s).

BACKGROUND

Surgical tools are used in the healthcare field to, for example, affect (e.g., cut, remove, cauterize, etc.) an anatomical part during a surgical procedure. Generally, each surgical tool is configured to perform a specific function. Accordingly, it can be necessary for a professional to use multiple surgical tools during a surgical procedure when different functions are needed to complete the surgical procedure.

SUMMARY

The inventor has discovered that when a professional uses multiple surgical tools, manual actions of switching between the two surgical tools can be very time consuming, and can lead to increase in associated costs.

The disclosure herein provides improved handheld surgical devices and methods related to the handheld surgical devices. Some of the embodiments of the handheld surgical devices described herein are configured with a working portion that is covered (e.g., when not being used), and then uncovered (e.g., when it is being used). For example, the working portion can be retracted to be covered when it is not being used, but then the working portion is extended to be uncovered when it is being used. Further, when the working portion is covered, the part that covers the working portion can include another working portion that is configured for performing a different procedure. Thus, some of the embodiments of the handheld surgical devices can be used to perform two or more specific functions. Advantageously, the embodiments of the handheld surgical devices described herein can reduce and/or eliminate the need for switching between surgical devices during performance of a surgical procedure. Thus, there can be savings in time, related costs, or both.

In some embodiments, the handheld surgical device has a distal portion and a proximal portion. The terms “proximal” and “distal” are used herein to indicate portions of the handheld surgical device with respect to an operator's hand. That is, the proximal portion is close to the operator's hand than the distal portion of the handheld surgical device. The proximal portion includes a handle configured for being held by an operator's hand. A switch is disposed at the proximal portion (e.g., handle), and the switch is configured to operate the distal portion so that at least a part of the distal portion covers the working portion. The switch can also be configured operate the distal portion to uncover the working portion.

In some embodiments, the working portion includes a cutting blade. The cutting blade can be configured for cutting soft tissue, but not bone.

In some embodiments, the working portion includes a drill. The drill can be configured for cutting bone, drilling into bone, or both.

In some embodiments, the working portion is driven by a motor disposed at the proximal portion connected to a power supply.

In some embodiments, the distal portion of the handheld surgical device which covers the working portion includes a shroud.

In some embodiments, the shroud and/or a part of the distal portion includes a cutting edge, wherein the cutting edge is configured to perform a function that is different from the working portion.

In some embodiments, the cutting edge is configured for cutting soft tissue.

In some embodiments, the working portion is driven by a motor to cut and/or drill bone.

In some embodiments, the cutting edge is operable by manual movement of the operator, and the cutting edge is not driven by a motor.

DETAILED DESCRIPTION

Generally, a working portion of a handheld surgical device is configured for performing a specific function during a medical procedure that is performed by a healthcare professional. During the medical procedure, it can be necessary for the healthcare profession to switch between different handheld surgical devices at the same or near an anatomical location, such as a wound. For example, a device for cutting and removing soft tissue may be used, and then, when that device nears a bone, a different device may be needed to cut away the bone. Switching between different handheld surgical devices repeatedly within the wound to complete an operation can increase the operation time and associated costs. Further, switching between different surgical devices may require the healthcare professional to take her eyes off of the anatomical region (e.g., wound) and also may require additional mental concentration in order to acquire the correct tool for the needed function in the anatomical region. Accordingly, alternating between several tools can be tedious and may increase the fatigue of the healthcare professional, risk of contamination, infection, and/or damage to the patient. The contamination, infection, and/or intended damage can cause or exacerbate problems for a patient and a treatment plan. Thus, there is a clear advantage for a handheld surgical device which can reduce and/or eliminate the tedious alternation between different tools.

The handheld surgical devices described herein can provide multiple tools and/or functions in a single device. Thus, the handheld surgical devices described herein can reduce and/or eliminate the tedious alternation between different tools.

An embodiment of a handheld surgical device described herein includes a shroud that extends from a working portion disposed on a distal portion and a cutting blade within a neck portion of the distal portion, from which the cutting blade can be retracted and advanced based on the setting of a switch. The shroud portion of the handheld surgical device can include a cup portion that can function independently of the cutting blade.

FIG. 1 shows a schematic illustration of a handheldsurgical device100, according to an embodiment. The handheldsurgical device100 includes aproximal portion102 and adistal portion104. Theproximal portion102 includes ahandle106 configured for a user's hand to hold, preferably comfortably, while the handheldsurgical device100 is being used. Thedistal portion104 includes a workingportion108. At least a part of the workingportion108 is configured for being inserted into a wound or an anatomical area to perform a function (e.g., drill bone, cut tissue, etc.) during a surgical procedure.

In some embodiments, thedistal portion104 can be attached and/or detached from theproximal portion102 at anattachment region110. For example, thedistal portion104 can be detached from theproximal portion102 at theattachment region110 after use in a surgical procedure, and then a new (i.e., unused)distal portion104 can be attached to theproximal portion102 at theattachment region110 before being used in another surgical procedure.

Alternatively, thedistal portion104 can be removed and cleaned/sanitized before being reattached to theproximal portion102 for future use. That is, thedistal portions104 can be disposed of after use, or be sanitized after use for reuse.

Thedistal portion104 includes aneck portion112, which extends from theattachment region110 to the workingportion108.

The workingportion108 of the handheldsurgical device100 can be covered by a shroud114 (or a cover) disposed at or near the end of thedistal portion104. Theshroud114 can be, for example, cup-shaped and have acutting edge116. In some embodiments, theshroud114 can be a concave shaped portion, a hooded cover, or be a partially enclosed scoop. For example, theshroud114 can be configured for cutting and/or scooping soft tissue, without requiring a powered motor, while the workingportion108 is connected to a motor and a power supply so that the motor drive the workingportion108 so that the workingportion108 can cut or drill into hard tissue and/or bone.

Advantageously, a healthcare professional can use the handheldsurgical device100 for at least two different functions (e.g., for affecting different anatomical regions). Thus, the handheldsurgical device100 can eliminate the need for manually switching between two different surgical tools (e.g., for cutting soft tissue and for cutting bone) during a surgical procedure.

The workingportion108 can be uncovered by theshroud114 by, for example, being extended outward from theshroud114. Theproximal portion102 of the handheldsurgical device100 includes aswitch118 disposed at or near thehandle106, wherein theswitch118 can include a first setting for uncovering the workingportion108 and a second setting for covering the workingportion108.

In some embodiments, the length of the workingportion108 is at least 0.5 mm. In some embodiments, the length of the workingportion108 is at least 1.0 mm. In some embodiments, the length of the workingportion108 is at most 10.0 mm. In some embodiments, the length of the workingportion108 can be approximately from 0.5 mm to 10 mm. In some embodiments, the length of the workingportion108 can be approximately from 1 mm to 10 mm.

The handheldsurgical device100 can be of various shapes and sizes.

FIGS. 2A and 2B illustrate schematic side views of a handheldsurgical device200, according to an embodiment. The handheldsurgical device200 includes aproximal portion202, adistal portion204, ahandle206, a workingportion208, anattachment region210, aneck portion212, ashroud214, acutting edge216, and aswitch218, wherein these elements are similar to the like features shown and described with respect toFIG. 1.

Theproximal portion202 includes amechanism220 that is connected to theswitch218 and to the workingportion208, wherein themechanism220 is configured to change the position of the working portion208 (e.g., extended position or retracted position) based in a user's input via theswitch218.

The workingportion208 includes acutting blade222 driven by amotor224 that is powered by apower supply226. Themotor224 and thepower supply226 are disposed in theproximal portion202. Anotherswitch228 is configured to activate themotor224 to drive thecutting blade222.

FIG. 2A shows the workingportion208 in the retracted position (operable by the switch218), wherein the workingportion208 is substantially disposed inside acavity230 in theneck portion212. This allows for thecutting edge216 to be used (e.g., for cutting soft tissue) without being hindered by the workingportion208.

FIG. 2B shows thecutting blade222 and/or the workingportion208 in the extended position (operable by the switch218), wherein thecutting blade222 and/or the workingportion208 is extended out of thecavity230 and positioned distally away from thecutting edge216. This allows for thecutting blade222 and/or the workingportion208 to be used (e.g., for cutting bone) without being hindered by thecutting edge216. Theshroud214 is disposed at a location away from thecutting blade222 and/or the workingportion208, so that theshroud214 can be used to shield and/or protect an anatomical region when the workingportion208 is being used. For example, the position of theshroud214 with respect to theextended cutting blade222 and/or extended workingportion208 provides theshroud214 to be used for pushing away tissue or other anatomical regions that the user does not desire to be affected (e.g., cut, drill, etc.) by theextended cutting blade222 and/or the extended workingportion208.

In some embodiments, thecutting blade222 can be a cutting burr made composed of diamond, carbide or like material, and having an oval, matchstick, pear, twist drill, a fluted ball, or the like shape. In some embodiments, thecutting blade222 can take the shape and/or components of traditional burrs.

When thecutting blade222 is retracted (e.g., not functioning), thecutting edge216 of theshroud214 can function. For example, in an embodiment where theshroud214 has a cup-like shape (e.g., scoop-shaped), theshroud214 can be used to scoop and/or gather tissue, bone, blood, and/or the like during the surgical procedure. Further, thecutting edge216 can function to cut soft tissue, soft bone, and/or a line during the surgical procedure. Because thecutting edge216 is not powered by a motor, thecutting edge216 can function to cut soft tissue and/or soft bone. However, thecutting blade222, which is driven by a motor, can function to cut harder tissue and/or bone.

Thepower supply226 can be a battery, a unit for converting AC to DC with a cord for connecting to an AC source, an air pressure unit (i.e., the motor is driven by pressurized air or suction), etc. Thepower supply226 can power themotor224, which can cause thecutting blade222 to rotate. Thecutting blade222 can rotate at speeds capable of cutting through tissue, bone, or the like during a surgical procedure.

FIG. 3 illustrates a method flow diagram300 for using the handheld surgical device, according to an embodiment. Atstep302, a user connects a proximal portion (e.g.,202 shown inFIG. 2A) and a distal portion (e.g.,204 shown inFIG. 2A) of the handheld surgical device (e.g.,200 shown inFIG. 2A). Thisstep302 can include attaching a different (e.g., new) distal portion to the proximal portion and activating a locking mechanism on the proximal portion to lock the distal portion in place. The different distal portion can be added and/or detached for each new surgical procedure such that the risk of infection and/or contamination is decreased.

Atstep304, the user can use the handheld surgical device for cutting tissue, by using a cutting edge or a cutting blade (e.g., the working portion), based on whether the working portion is extended or retracted.

Atstep306, the user can extend or retract the working portion, and then atstep304, use the handheld surgical device for cutting tissue or bone, by using the cutting edge or the working portion (e.g., the cutting blade). When the user retracts the working portion so that the working portion is no longer operable, the user can use the handheld surgical device for cutting tissue with the cutting edge. Retracting the cutting blade includes disabling the operation to cut a removal portion with the cutting blade. In some embodiments, retracting the cutting blade completely protects the cutting blade via inside the neck portion of the handheld surgical device. That is, retracting the cutting blade disables the operation to cut a removal portion as it is nestled inside the neck portion of the surgical device and not protected by the shroud, as described herein. In some embodiments, the cutting blade and/or the working portion can be partially protected by a shroud while enabling an operation to cut a removal portion in the anatomy. A removal portion, as used herein, is a portion to be removed and/or cut during a surgical procedure. For example, a removal portion can be an area of bone, tissue, blood, or the like Additionally, the shroud can partially cover the cutting blade so as to protect areas that are not meant to be cut (e.g., non-removal portions). Step306 can include powering a motor connected to the cutting blade such that the cutting blade rotates at a speed capable of cutting bone. That is, power can be provided to a motor associated with the cutting blade such that the cutting blade can rotate and cut the removal portion.

Atstep308, the user can disconnect the proximal portion and the distal portion. Then the distal portion can be discarded or sanitized for reuse. The distal portion can be removed from the proximal portion at an attachment region, as described herein. Disposing of the distal portion can decrease cross-contamination and/or cross-infection between patients receiving surgical procedures. For instance, using a new distal portion for each patient can significantly reduce contamination and infections risks. In some embodiments, the distal portion can be detached and cleaned before being reattached to the proximal portion. For instance, the distal portion may be detached and cleaned via autoclaving, sanitization procedures, soap, alcohol, and/or the like. The cleaned and/or sanitized distal portion can be reattached to the proximal portion for future use.

The steps shown inFIG. 3 can be performed in various sequences and/or combinations. In particular, the flowchart shown inFIG. 3 provides for performing the steps according to one or more of the exemplary orders and/or sequences listed below (but not necessarily limited only to these orders):

FIG. 4 shows a schematic side view of another embodiment of the handheldsurgical device400. The handheldsurgical device400 includes aproximal portion402, adistal portion404, ahandle406, a workingportion408, anattachment region410, aneck portion412, ashroud414, acutting edge416, and aswitch418. Theproximal portion402 includes amechanism420 that is connected to theswitch418 and to the workingportion408, wherein themechanism420 is configured to change the position of the working portion408 (e.g., extended position or retracted position) based in a user's input via theswitch418. The workingportion408 includes acutting blade422 driven by amotor424 that is powered by apower supply426. Themotor424 and thepower supply426 are disposed in theproximal portion402. Anotherswitch428 is configured to activate themotor424 to drive thecutting blade422. The workingportion408 can be placed in the retracted position (operable by the switch418), wherein the workingportion408 is substantially disposed inside acavity430 in theneck portion412. This allows for thecutting edge416 to be used (e.g., for cutting soft tissue) without being hindered by the workingportion408.FIG. 4 shows thecutting blade422 and/or the workingportion408 in the extended position (operable by the switch418), wherein thecutting blade422 and/or the workingportion408 is extended out of thecavity430 and positioned at least partly within a space that is at least partly surrounded by theshroud414. For example, if theshroud414 is a concave scoop-like configuration, then at least part of thecutting blade422 and/or the workingportion408 is contained in the concave scoop-like shape, as shown inFIG. 4. Thus, theshroud414 can be used to shield and/or protect an anatomical region when thecutting blade422 and/or the workingportion408 is being used. A top view of aportion500 of thedistal portion404 is shown inFIG. 5. Theportion500, when viewed from above, shows thecutting blade422 and/or the workingportion408 contained in the concave scoop-like shape of theshroud414 when the workingportion408 is in the extended configuration.
